### Issue with current documentation:
The sample code in https://github.com/langchain-ai/langchain/blob/master/cookbook/oracleai_demo.ipynb uses try/catch blocks which don't print the actual driver or DB error, making it impossible to troubleshoot. For example it currently has:
```
import sys
import oracledb
# please update with your username, password, hostname and service_name
username = ""
password = ""
dsn = ""
try:
conn = oracledb.connect(user=username, password=password, dsn=dsn)
print("Connection successful!")
except Exception as e:
print("Connection failed!")
sys.exit(1)
```
For any connection failure this will only show:
```
Connection failed!
```
The code should be changed to:
```
import sys
import oracledb
# please update with your username, password, hostname and service_name
username = ""
password = ""
dsn = ""
conn = oracledb.connect(user=username, password=password, dsn=dsn)
print("Connection successful!")
```
This, for example, with an incorrect password will show a traceback and a useful error:
```
oracledb.exceptions.DatabaseError: ORA-01017: invalid credential or not authorized; logon denied
Help: https://docs.oracle.com/error-help/db/ora-01017/
```
The same try/catch problem exists in other examples.

messages = state["messages"]

code_gen_chain = llm.with_structured_output(Code, include_raw=False)
code_solution = code_gen_chain.invoke(messages)
```
`code_solution` is always a `dict` not type `Code`.
### Error Message and Stack Trace (if applicable)
_No response_
### Description
This is code from a recent public codestral demo:
```
class Code(BaseModel):
prefix: str = Field(description="Description of the problem and approach")
imports: str = Field(description="Code block import statements")
code: str = Field(description="Code block not including import statements")
messages = state["messages"]
...
llm = ChatMistralAI(model="codestral-latest", temperature=0, endpoint="https://codestral.mistral.ai/v1")
code_gen_chain = llm.with_structured_output(Code, include_raw=False)
code_solution = code_gen_chain.invoke(messages)
```
`code_solution` is always a `dict` not type `Code`.
Stepping into `llm.with_structured_output`, the first lines are:
```
if kwargs:
raise ValueError(f"Received unsupported arguments {kwargs}")
is_pydantic_schema = isinstance(schema, type) and issubclass(schema, BaseModel)
```
`issubclass(schema, BaseModel)` always returns False even though `schema` is the same `Code` type being sent in.
Before the call:
```
>>> Code
<class 'codestral.model.Code'>
>>> issubclass(Code, BaseModel)
True
>>> type(Code)
<class 'pydantic._internal._model_construction.ModelMetaclass'>
```
Step inside the call:
```
>>> schema
<class 'codestral.model.Code'>
>>> issubclass(schema, BaseModel)
False
>>> type(schema)
<class 'pydantic._internal._model_construction.ModelMetaclass'>
```
It behaves correctly outside the call to Langchain and incorrectly inside the call.

QUESTION Can you please summarize this conversation?
RESPONSE: I'm sorry, but as an AI, I don't have the ability to summarize the current conversation. However, I can assist you with any specific questions or tasks you have. How can I help you today?
### Description
I'm trying to use the ConversationBufferWindowMemory from Langchain on a Agent with Tools.
I create the agent and load the memory but when I ask a question about a past message or ask for a summary it does not respond well.
I implemented a solution to add the messages manually in the prompt and it gave me this response.
Expected Response: The conversation so far has been brief. The user asked a simple math question, "What is 2+2?". I provided the answer, which is 4. There hasn't been any further discussion or questions.
But using Langchain ConversationBufferWindowMemory I responds.
Response: "I'm sorry, but as an AI, I don't have the ability to summarize the current conversation. However, I can assist you with any specific questions or tasks you have. How can I help you today?"
Memory Content:
Memory content [HumanMessage(content='What is 2+2'), AIMessage(content='The answer to 2+2 is 4'), HumanMessage(content='Can you please summarize this conversation?'), AIMessage(content="I'm sorry, but as an AI, I don't have the ability to summarize the current conversation. However, I can assist you with any specific questions or tasks you have. How can I help you today?")]
Have any of you found this issue before? How can I make the Agent use the Memory?

Using the example code in the tutorial provided the plugin usage from URL does not work anymore:

from langchain_openai import ChatOpenAI
from langchain import hub
from langchain.agents import AgentExecutor, create_structured_chat_agent
tool = AIPluginTool.from_plugin_url("https://www.klarna.com/.well-known/ai-plugin.json")
llm = ChatOpenAI(temperature=0)
tools = load_tools(["requests_all"])
tools += [tool]
prompt = hub.pull("hwchase17/structured-chat-agent")
agent = create_structured_chat_agent(llm, tools, prompt)
agent_executor = AgentExecutor(agent=agent, tools=tools,handle_parsing_errors=False, verbose=True,include_run_info=False)
result = agent_executor.invoke({"input":"what t shirts are available in klarna?"})
```
The same with deprecated call structure.
```python
from langchain_community.tools import AIPluginTool
from langchain.agents import AgentType, initialize_agent, load_tools
from langchain_openai import ChatOpenAI
tool = AIPluginTool.from_plugin_url("https://www.klarna.com/.well-known/ai-plugin.json")

agent_chain.run("What are some t shirts available on Klarna?")

Usage Guide: Assistant uses the Klarna plugin to get relevant product suggestions for any shopping or product discovery purpose. Assistant will reply with the following 3 paragraphs 1) Search Results 2) Product Comparison of the Search Results 3) Followup Questions. The first paragraph contains a list of the products with their attributes listed clearly and concisely as bullet points under the product, together with a link to the product and an explanation. Links will always be returned and should be shown to the user. The second paragraph compares the results returned in a summary sentence starting with "In summary". Assistant comparisons consider only the most important features of the products that will help them fit the users request, and each product mention is brief, short and concise. In the third paragraph assistant always asks helpful follow-up questions and end with a question mark. When assistant is asking a follow-up question, it uses it's product expertise to provide information pertaining to the subject of the user's request that may guide them in their search for the right product.

as you can see 3 documents are the same.
I checked and splits contain 52 documents, but the value of
```
res = vectorstore.get()
res.keys()
len(res['documents'])
```
is 156, so I think each document is stored 3 times instead of 1.

### Description
I am trying to instantiate a Human-as-a-Tool tool, without the load_tools function, this way it would be easier to integrate it in the rest of my app. However, strange things start to happen when I do this direct instantiation. It seems LangChain does not recognize the tool properly, please advise. Cheers.

### Description
* I am trying to use Langchain to create an Agent that call tools and has memory.
* When I use the astream_events API, the messages generated by the AI before calling a tool (e.g when 'finish_reason' is 'tool_calls') are not saved into the ChatMessageHistory.
What is currently happening :
* As you can see in the stack trace, the message sent by the AI before calling the tool does not appear in the Agent history.
What I expect to happen:
* The AIMessageChunk generated before "finish_reason" is "tool_calls" appears in the agent message history
Please let me know if anything is unclear or if the problem lies with my implementation.
Thanks in advance,

- [X] I added a very descriptive title to this issue.

- [X] I am sure that this is a bug in LangChain rather than my code.
- [X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).
### Example Code
I don't have a MRE, but better to tell you what I know than nothing at all: after updating to latest 0.2.x from 0.1.x, I started having this warning. It comes from `lanchain_core/tracers/base.py:399`. I noticed that `chain_run` is of class `RunTree` rather than `Run`, it looks like `self.run_map` in that function contains a mix of `Run` and `RunTree` objects, of which only the `Run` objects have an `events` defined?

response = llm.invoke(messages)
response.content
```
### Error Message and Stack Trace (if applicable)
I get the following response, still with exclamation marks:
"ARE YOU KIDDING ME RIGHT NOW?! I CAN'T BELIEVE YOU WOULD DO SOMETHING SO ABSURD AND THOUGHTLESS!! THIS IS COMPLETELY UNACCEPTABLE AND I AM BEYOND FURIOUS!! HOW COULD YOU POSSIBLY THINK THIS WAS A GOOD IDEA?! YOU HAVE CROSSED THE LINE AND I AM DONE PUTTING UP WITH THIS NONSENSE!! GET YOUR ACT TOGETHER IMMEDIATELY OR THERE WILL BE SERIOUS CONSEQUENCES!!"
### Description
As you can see, it is not having the desired effect. I have also tried passing the logit bias dictionary to llm.invoke instead:
```
from langchain_openai import ChatOpenAI
logit_bias_dict = {'0': -100}
llm = ChatOpenAI(
api_key=os.getenv("OPENAI_API_KEY"),
model="gpt-4o",
temperature=0,
)
messages = [("human", "Write me a furious message as though you are screaming")]
response = llm.invoke(messages, **{"logit_bias": logit_bias_dict})
response.content
```
which also has no effect. Conversely this works fine with OpenAI directly.
I have also tried using 0 instead of '0' (i.e. an integer instead of a string) - also no difference.

### Example Code
```
from pydantic import BaseModel, Field
from typing import List
from langchain_openai import ChatOpenAI
class Jokes(BaseModel):
"""List of jokes to tell user."""
jokes: List[str] = Field(description="List of jokes to tell the user")
structured_llm = ChatOpenAI(model="gpt-4").with_structured_output(Jokes)
structured_llm.invoke("You MUST tell me more than one joke about cats")
```
### Error Message and Stack Trace (if applicable)
_No response_
### Description
I'm trying to get a structured output using a chain with `ChatOpenAI`. I reproduced the behavior with this very simple scenario:
```
from pydantic import BaseModel, Field
from typing import List
from langchain_openai import ChatOpenAI
class Jokes(BaseModel):
"""List of jokes to tell user."""
jokes: List[str] = Field(description="List of jokes to tell the user")
structured_llm = ChatOpenAI(model="gpt-4").with_structured_output(Jokes)
structured_llm.invoke("You MUST tell me more than one joke about cats")
```
I expected the result to be a list of jokes, but it didn't work, even for this very simple prompt. If I change the code a little bit like this:
```
class Jokes(BaseModel):
"""List of jokes to tell user."""
jokes: str = Field(description="List of jokes to tell the user, separated by a semicolon")
structured_llm = ChatOpenAI(model="gpt-4").with_structured_output(Jokes)
structured_llm.invoke("You MUST tell me more than one joke about cats, and split them with a semicolon")
```
I get the following output:
```
{'jokes': "Why don't cats play poker in the jungle? Too many cheetahs.;What do you call a cat that throws all the most expensive parties? The Great Catsby.;Why did the cat sit on the computer? To keep an eye on the mouse."}
```
Obviously, the model knows how to solve such a simple task, but it doesn't seem to be using the structure correctly when it has a list of strings as the attribute.
I tried the same behavior with more complex structured outputs, and the same happened.

### Description
- **Problem**: Encountering `FileNotFoundError: [Errno 2] No such file or directory` when trying to use `PineconeVectorStore.from_documents` in an AWS Lambda environment with the base image `python:3.11-slim`.
- **Expected Behavior**: The code should initialize a `PineconeVectorStore` retriever without errors.
- **Actual Behavior**: The initialization fails with a `FileNotFoundError` indicating an issue with multiprocessing in the slim Python 3.11 Docker image.

I am referring to the code of langchain for self-query retriever.
But when I try the below query it throws an error.
output1:
output2:
both queries have the same meaning but there is a problem in response,
where output1 is successful but output2 throws error.
What can be the reason?

### Example Code
The following code from AzureSearch class
```
def delete(self, ids: Optional[List[str]] = None, **kwargs: Any) -> bool:
"""Delete by vector ID.
Args:
ids: List of ids to delete.
Returns:
bool: True if deletion is successful,
False otherwise.
"""
if ids:
res = self.client.delete_documents([{"id": i} for i in ids])
return len(res) > 0
else:
return False
```
Do not use the FIELDS_ID variable defined at the top of the script therefore it doesn't allow complete override of the key field in Azure AI Search.
Simply replacing by:
```
def delete(self, ids: Optional[List[str]] = None, **kwargs: Any) -> bool:
"""Delete by vector ID.
Args:
ids: List of ids to delete.
Returns:
bool: True if deletion is successful,
False otherwise.
"""
if ids:
res = self.client.delete_documents([{FIELDS_ID: i} for i in ids])
return len(res) > 0
else:
return False
```
Will do the trick.

```
### Description
In the documentation here: https://api.python.langchain.com/en/latest/vectorstores/langchain_community.vectorstores.faiss.FAISS.html#langchain_community.vectorstores.faiss.FAISS.load_local
It says that I can use the asynchronous argument to use the async version. However, when I try it, I get the stack trace such that FAISS.__init__() got an unexpected keyword argument 'asynchronous'.
It is possible I am misunderstanding the usage of this feature. In the example code, I am simply trying to call load_local with this argument.

### Checklist
- [X] I added a very descriptive title to this issue.
- [X] I included a link to the documentation page I am referring to (if applicable).
### Issue with current documentation:
In the following documentation url. The row on ChatOpenAI shows Streaming not supported.
**https://python.langchain.com/v0.1/docs/integrations/chat/**
While the there is a documentation page show it is supported:
**https://python.langchain.com/v0.1/docs/modules/agents/how_to/streaming/**
I'm just wondering if my dyslexia and poor eyesight are playing tricks on me.
### Idea or request for content:
Your page says steaming is not support while another page provides a short notebook.
I think they should be consistent. It could be I do not understand the what is on the following page

"langchain-ai",
"langchain"
] | ## Issue
To make our chat model integrations as easy to use as possible we need to make sure the docs for them are thorough and standardized. There are two parts to this: updating the chat model docstrings and updating the actual integration docs.
This needs to be done for each ChatModel integration, ideally with one PR per ChatModel.
Related to broader issues #21983 and #22005.
## Docstrings
Each ChatModel class docstring should have the sections shown in the [Appendix](#appendix) below. The sections should have input and output code blocks when relevant. See ChatOpenAI [docstrings](https://github.com/langchain-ai/langchain/blob/f39e1a22884005390a3e5aa2beffaadfdc7028dc/libs/partners/openai/langchain_openai/chat_models/base.py#L1120) and [corresponding API reference](https://api.python.langchain.com/en/latest/chat_models/langchain_openai.chat_models.base.ChatOpenAI.html) for an example.
To build a preview of the API docs for the package you're working on run (from root of repo):
```bash
make api_docs_clean; make api_docs_quick_preview API_PKG=openai
```
where `API_PKG=` should be the parent directory that houses the edited package (e.g. community, openai, anthropic, huggingface, together, mistralai, groq, fireworks, etc.). This should be quite fast for all the partner packages.
## Doc pages
Each ChatModel [docs page](https://python.langchain.com/v0.2/docs/integrations/chat/) should follow [this template](https://github.com/langchain-ai/langchain/blob/master/libs/cli/langchain_cli/integration_template/docs/chat.ipynb). See [ChatOpenAI](https://python.langchain.com/v0.2/docs/integrations/chat/openai/) for an example.
You can use the `langchain-cli` to quickly get started with a new chat model integration docs page (run from root of repo):
```bash
poetry run pip install -e libs/cli
poetry run langchain-cli integration create-doc --name "foo-bar" --name-class FooBar --destination-dir ./docs/docs/integrations/chat/
```
where `--name` is the integration package name without the "langchain-" prefix and `--name-class` is the class name without the "Chat" prefix. This will create a template doc with some autopopulated fields at docs/docs/integrations/chat/foo_bar.ipynb.
To build a preview of the docs you can run (from root):
```bash
make docs_clean
make docs_build
cd docs/build/output-new
yarn
yarn start
```

### Example Code
I can reproduce it with this simple example:

@chain
def four(input):
return 'four'
print(four.get_graph().draw_mermaid())
```
### Error Message and Stack Trace (if applicable)
It produces this Mermaid:
```

graph TD;
four_input:::startclass;
Lambda_four_([Lambda(four)]):::otherclass;
four_output:::endclass;
four_input --> Lambda_four_;
Lambda_four_ --> four_output;
classDef startclass fill:#ffdfba;
classDef endclass fill:#baffc9;
classDef otherclass fill:#fad7de;
```
Which is invalid:
```
Error: Parse error on line 3:

```
It can be fixed by adding quotes to the node label:
```
Lambda_four_([Lambda(four)]):::otherclass;
# should be:
Lambda_four_(["Lambda(four)"]):::otherclass;
```
### Description
Perhaps I'm missing something, but when using the draw_mermaid() function on a chain/runnable it outputs incorrect mermaid syntax.

### Example Code
### Example Code to Reproduce
```python
from langchain.textsplitters import MarkdownHeaderTextSplitter
# Sample Markdown input
markdown_text = """
# My Heading
This is a paragraph with some detailed explanation.
This is another separate paragraph.
"""
# Initialize and apply the text splitter
splitter = MarkdownHeaderTextSplitter(headers_to_split_on=[('#', 'Header 1')])
result = splitter.split_text(markdown_text)
print(result)
```
### Expected Behavior
The expected behavior would be to keep the paragraph breaks as they are crucial for subsequent text manipulation tasks that may rely on the structure conveyed by separate paragraphs:
```python
[Document(page_content='This is a paragraph with some detailed explanation.\n\nThis is another separate paragraph.', metadata={'Header 1': 'My Heading'})]
```
### Actual Behavior
Currently, the text after being processed by `MarkdownHeaderTextSplitter` loses paragraph distinctions, flattening into line breaks:
```python
[Document(page_content='This is a paragraph with some detailed explanation.\nThis is another separate paragraph.', metadata={'Header 1': 'My Heading'})]
```
This issue affects not only readability but also the downstream processing capabilities that require structured and clearly delineated text for effective analysis and feature extraction.

The current implementation of `MarkdownHeaderTextSplitter` in LangChain notably [splits on text on `/n`](https://github.com/relston/langchain/blob/d268587cbadded8cf1a3d67546afafe5db0690c5/libs/text-splitters/langchain_text_splitters/markdown.py#L96) and [strips out white space](https://github.com/relston/langchain/blob/d268587cbadded8cf1a3d67546afafe5db0690c5/libs/text-splitters/langchain_text_splitters/markdown.py#L111) from each line when processing Markdown text. This removal of white spaces and paragraph separators (`\n\n`) directly impacts further text splitting and processing strategies, as it disrupts the natural paragraph structure integral to most textual analyses and transformations.
### Other Examples
The white-space-stripping implementation of this text splitter also has been previously identified to be problematic by other users use-cases, as evidenced by issues [#20823](https://github.com/langchain-ai/langchain/issues/20823) and [#19436](https://github.com/langchain-ai/langchain/issues/19436).

### Description
Hello all.
I am experiencing an issue when using ConversationalRetrievalChain with multiple vectorstores and merging them. I notice that when querying, the content returned is not complete. Upon checking, I found that the content is divided into two parts, but the query only retrieves the first part. How can I resolve this issue? and ConversationalRetrievalChain does not correctly answer some questions in the document

### Issue with current documentation:
[A recent Microsoft announcement](https://techcommunity.microsoft.com/t5/ai-azure-ai-services-blog/announcing-key-updates-to-responsible-ai-features-and-content/ba-p/4142730) revealed that they made [the Azure OpenAI asynchronous filtering](https://learn.microsoft.com/en-us/azure/ai-services/openai/concepts/content-filter?tabs=warning%2Cpython#content-streaming) generally available, which is fantastic. However, when I tried to use it, I continued to experience buffering in streamed responses and therefore a poor UX from Azure's endpoints (vs. OpenAI's direct endpoints).
### Idea or request for content:
After [the journey discussed here](https://github.com/langchain-ai/langchain/discussions/22246), I discovered that the issue was the API version I was passing to `AzureChatOpenAI`: I was passing `2023-05-15`, which was previously the last stable version, whereas I needed to update to `2024-02-01` instead.
[The current LangChain documentation page](https://python.langchain.com/v0.1/docs/integrations/llms/azure_openai/) suggests `2023-12-01-preview` as the version to use — but Microsoft has been sunsetting these preview API releases and it doesn't seem wise to depend on them in production. Rather, `2024-02-01` is the current recommended GA API version, and it seems to work well. I recommend updating the documentation accordingly. | DOC: Azure OpenAI users should be counseled to specify 2024-02-01 as the API version, otherwise streaming support will be buffered | https://api.github.com/repos/langchain-ai/langchain/issues/22252/comments | 1 | 2024-05-28T22:22:54Z | 2024-06-01T14:19:25Z | https://github.com/langchain-ai/langchain/issues/22252 | 2,322,013,722 | 22,252 |

2. Do not use EXISTS, SIZE keywords in the cypher. Use alias when using the WITH keyword
3. Please do not use same variable names for different nodes and relationships in the query.
4. Use only Nodes and relationships mentioned in the schema
5. Always enclose the Cypher output inside 3 backticks
6. Always do a case-insensitive and fuzzy search for any properties related search. Eg: to search for a Company name use `toLower(c.name) contains 'neo4j'`
7. Candidate node is synonymous to Manager
8. Always use aliases to refer the node in the query
9. 'Answer' is NOT a Cypher keyword. Answer should never be used in a query.
10. Please generate only one Cypher query per question.
11. Cypher is NOT SQL. So, do not mix and match the syntaxes.
12. Every Cypher query always starts with a MATCH keyword.
13. Always do fuzzy search for any properties related search. Eg: when the user asks for "matrix" instead of "the matrix", make sure to search for a Movie name using use `toLower(c.name) contains 'matrix'`

### Description
I am trying to use Google Gemini 1.5 Pro API key from Google AI Studio in the above code and getting the error:
```Retrying langchain_google_genai.chat_models._chat_with_retry.<locals>._chat_with_retry in 2.0 seconds as it raised ResourceExhausted: 429 Resource has been exhausted (e.g. check quota)..```
This doesn't seem right as the API call was made only twice. I tried switching to ```gemini-1.5-flash``` and it seems to work fine. I am assuming this has something to relate to gemini 1.5 pro's implementation with langchain. Quoting one of the replies in a "somewhat" similar [issue](https://www.googlecloudcommunity.com/gc/AI-ML/Gemini-API-429-Resource-has-been-exhausted-e-g-check-quota/m-p/728855):
> My theory is that the gemini-pro-1.5-latest endpoint has some sort of other limit, that we as users can't see when using the "generativeai" python SDK. The only thing that shows up in metrics is failed API calls, but NOT limit hits.
The way around this, I believe, would be to directly use the Vertex SDK directly, not the GenAI API.

### Example Code
Steps to Reproduce
1. Use the add_documents function to process a list of documents.
2. Occasionally observe that some points are duplicated, having different IDs but the same content.
Here is the code we are using:
```
@retry(tries=3, delay=2)
def _load_vectordatabase(self, docs_chunks: tp.List[Document]) -> list:
point_list= self.add_documents(docs_chunks)
return point_list
```
https://github.com/langchain-ai/langchain/blob/master/libs/community/langchain_community/vectorstores/qdrant.py
### Error Message and Stack Trace (if applicable)
_No response_
### Description
Using Qdrant vector store we have encountered an issue where duplicate points with different IDs but the same content are being generated when using the add_documents and add_texts functions in the Langchain library. The duplication appears to be random and occurs infrequently, making it challenging to consistently reproduce.
It should not be possible for the same document resulting from a chunk to generate two points with the same duplicated content, and we are sure that it was not uploaded twice (besides, not all the page content is duplicated).

Modified code which uses max_inner_product distance generates the following output:
Relevance score by definition is between 0-1. 0 is dissimilar, 1 is most similar. See reference 1.
Reference code output produces valid relevance score, in which most similar document have relevant score closest to 1.
Modified code using MAX_INNER_PRODUCT, produces invalid relevance score, in which most similar document have relevant score most distant to 1. This contradicts with the definition of relevance score.

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
- [X] I am sure that this is a bug in LangChain rather than my code.
- [X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).
### Example Code
```python
from langchain_experimental.llms.ollama_functions import OllamaFunctions
from langchain.agents import AgentExecutor, create_tool_calling_agent, tool
from langchain_core.prompts.chat import ChatPromptTemplate, MessagesPlaceholder
@tool
def get_word_length(word: str) -> int:
"""Returns the length of a word"""
return len(word)
tools = [get_word_length]
prompt = ChatPromptTemplate.from_messages([
("system", "You are a helpfull assistant"),
("human", "{input}"),
MessagesPlaceholder("agent_scratchpad")
])
model = OllamaFunctions(model="mistral:7b-instruct-v0.3-q8_0", format="json")
agent = create_tool_calling_agent(model, tools, prompt)
agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=True)
result = agent_executor.invoke({
"input": "How many letters are in 'orange' ?"
})
print(result["output"])
```
Following the code presented in this langchain video : https://www.youtube.com/watch?v=zCwuAlpQKTM&ab_channel=LangChain the LLM should be able to call the tool `get_word_length`.

### Description
I should get the number of letters in the word "orange" as the tool should return it's length. Instead I get an exception about the tool.
Note that doing the following does return a correct JSON tool call.
```python
from langchain_experimental.llms.ollama_functions import OllamaFunctions
from langchain.agents import AgentExecutor, create_tool_calling_agent, tool
from langchain_core.prompts.chat import ChatPromptTemplate, MessagesPlaceholder
chatModel = OllamaFunctions(model="mistral:7b-instruct-v0.3-q8_0", format="json")
def get_current_weather(some_param):
print("got", str(some_param))
model = chatModel.bind_tools(
tools=[
{
"name": "get_current_weather",
"description": "Get the current weather in a given location",
"parameters": {
"type": "object",

},

}

)
from langchain_core.messages import HumanMessage
answer = model.invoke("what is the weather in Boston?")
print(answer.content)
print( answer.additional_kwargs["function_call"])
```
It seems to me that there is an incompatibility with the way the decorator is creating the pydantic definition. But it's just a guess.

html_header_splits = html_splitter.split_text(some_html)
```
Or
```python
from langchain_text_splitters import HTMLSectionSplitter
some_html = "..."
xslt_path = "/path/to/this_exists.xslt"
headers_to_split_on = [("h1", "Header 1"), ("h2", "Header 2")]
html_splitter = HTMLSectionSplitter(headers_to_split_on=headers_to_split_on, xslt_path=xslt_path)
html_header_splits = html_splitter.split_text(some_html)
```
In both cases assuming `this_exists.xslt` is a valid xslt file that exists at the location passed.
### Error Message and Stack Trace (if applicable)
File src/lxml/parser.pxi:743, in lxml.etree._handleParseResult()
File src/lxml/parser.pxi:670, in lxml.etree._raiseParseError()

### Description
There are a couple of bugs here:
1. if you pass a relative file path - `./this_exists.xslt` then `HTMLSectionSplitter` tries to turn it to an absolute path but uses the path to the langchain module (`{app_dir}/.venv/lib/python3.12/site-packages/langchain_text_splitters` in my case) rather than the path to the current working directory.
4. If you pass an absolute path, the variable `xslt_path` is never set ([see here](https://github.com/langchain-ai/langchain/blob/cccc8fbe2fe59bde0846875f67aa046aeb1105a3/libs/text-splitters/langchain_text_splitters/html.py#L290)) so the method errors because we're passing `None` to `lxml.etree`
I'll open a PR with a fix shortly.

### Checklist
- [X] I added a very descriptive title to this issue.
- [X] I included a link to the documentation page I am referring to (if applicable).
### Issue with current documentation:
Please go through this issues:
**Issue 1 :** In your official documentation it is clearly written to import this
```from langchain.output_parsers import PydanticToolsParser```
which is not the correct path and hence will show error always. Instead of this above import statement use this
```from langchain.output_parsers.openai_tools import PydanticToolsParser``` , it works well you can check the screenshot and please update your document for the same.
**Issue 2:** In the same documentation one more issue has been found, where after creating query_analyzer you just showed that to run directly but it will not work until you will not add these two statements with the code
``` from langchain.globals import set_debug set_debug(True)```
unless it will show some debug kind of error.
### Idea or request for content:

### Example Code
Here is an example that demonstrates the problem:
If I change the `batch_size` in `api.py` to a value that is larger than the number of elements in my list, everything works fine. By default, the `batch_size` is set to 100, and only the first 100 elements are handled correctly.

from langchain_community.document_loaders import TextLoader
from langchain.text_splitter import CharacterTextSplitter
from langchain_openai import OpenAIEmbeddings
from langchain_community.vectorstores import Chroma
from langchain_core.documents import Document

print(idx)
idx = index(

```
### Error Message and Stack Trace (if applicable)
_No response_
### Description
I've encountered a bug in the index function of Langchain when processing documents. The function behaves inconsistently during multiple runs, leading to unexpected deletions of documents. Specifically, when running the function twice in a row without any changes to the data, the first run indexes all documents as expected. However, on the second run, only the first batch of documents (batch_size=100) is correctly identified as already indexed and skipped, while the remaining documents are mistakenly deleted and re-indexed.

### Example Code
chunk_metadata = {'id': '***', 'source': '***', 'title': '***', 'chunk': 1, 'offset': 2475, 'page_number': 1, 'source_user_email': '*', 'source_system': '*', 'source_country': *', 'product_series_name': '*', 'document_language': 'English', 'document_confidentiality': '*', 'test_languages': ['Spanish', 'English', 'French']}
key_chunk= "***"
vector_store.add_documents(
documents=chunks_to_add, keys=keys_to_add
)
### Error Message and Stack Trace (if applicable)
No error message displayed
### Description
I have a document which I have split into different chunks.
The chunk metadata is the langchain_chunk.metadata
The chunks_to_add are the list of this chunk and the keys_to_add are the respective keys.
I try to add the documents to the vector store which is an Azure AI serch service.
In this azure AI search index in which I am loading the documents I have two different fields:
document_language is a field type STRING while test_languages is a field type STRINGCOLLECTION.
Once the code has run and the document has been added in the azure ai search index,
I obtain in the metadata field:
"metadata": "{\"id\": \"***\", \"source\": \"***\", \"title\": \"/***\", \"chunk\": 1, \"offset\": 2475, \"page_number\": 1, \"source_user_email\": \*\", \"source_system\": \"*\", \"source_country\": \"*\", \"product_series_name\": \"*\", \"document_language\": \"English\", \"document_confidentiality\": \"*\", \"test_languages\": [\"Spanish\", \"English\", \"French\"]}",
so the chunk_metadata dictionary has been correctly read and applied to the metadata field as a string,
but if I look at the two singular fields: document_language and test_languages what I see is the following:
"document_language": "English"
"test_languages": []
What I imagined would happen is that test_languages would have been the list that I have in metadata so ["Spanish", "English", "French"]
Why is this not happening? Is it a bug or the collection types fields are not supported by add_texts
I tried to find some information on this in the docs:

Hello evryone,
I am using ChatOpenAI & ConveresationChain to implement text-generation by AI and I am facing some problems on using that.
Above code, I got the result but can't get the expected result because system_prompt is not working. I already made sure the data is correctly inputed into PROMPT variable.
Of course AI message & Human Message is working well.
For just I think only system_prompt is not working now.
I am not sure how to fix that and could you please let me know what I need to solve them.
Thanks for hearing good sounds from you.

- [X] I am a LangChain maintainer, or was asked directly by a LangChain maintainer to create an issue here.
### Issue Content
Many of LangChain tools were created before function calling was a thing. Their names range from things like "python_repl" to "Github Pull Request".
Function calling is the standard now, and at least in OpenAI's case, they cannot contain spaces (they at least used to convert the schema to typescript)
While this is a slight breaking change (it's a prompting change), i think making them work out of the box for function/tool calling justifies the switch. | [Tools] Update prebuilt tools to remove spaces | https://api.github.com/repos/langchain-ai/langchain/issues/22099/comments | 0 | 2024-05-23T21:57:05Z | 2024-05-23T21:59:32Z | https://github.com/langchain-ai/langchain/issues/22099 | 2,313,917,801 | 22,099 |

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
- [X] I am sure that this is a bug in LangChain rather than my code.
- [X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).
### Example Code
```
python
from langchain_community.vectorstores import Clickhouse, ClickhouseSettings
settings = ClickhouseSettings(
username=USERNAME,
password=KEY,
host=HOST_NAME,
port=PORT_NUM,
table=EMBED_TABLE
)
docsearch = Clickhouse.from_documents(docs, embeddings, config=settings)
```
### Error Message and Stack Trace (if applicable)
_No response_
### Description
I'm trying to connect to a Clickhouse instance secured with HTTPS. Conventionally, you are supposed to pass secure=True.
However, langchain_community.vectorstores.clickhouse.ClickhouseSettings only supports HTTP.
Worked my way around it by adding the following to ```libs/community/langchain_community/vectorstores/clickhouse.py```:
```
python
self.client = get_client(
secure = True, #this is the addition
host=self.config.host,
port=self.config.port,
username=self.config.username,
password=self.config.password,
**kwargs,
)
```
This isn't the best practice. The only other way to make this work is using HTTP to interface with Clickhouse but owing to security concerns it is not a great idea.
The problem is that we can't pass this param in ClickhouseSettings as:
```
python
settings = ClickhouseSettings(
username=USERNAME,
password=KEY,
host=HOST_NAME,
port=PORT_NUM,
table=EMBED_TABLE,
secure = True #like this
)
```

### Description
I'm trying to implement a basic tutorial [Build a Chatbot]( https://python.langchain.com/v0.2/docs/tutorials/chatbot/) with a local Ollama llama3 model.
But I got the error `Error in RootListenersTracer.on_llm_end callback: KeyError('message')` and the functionality with history didn't work.
I made a debug and found that in RunnableWithMessageHistory class on [line 413](https://github.com/langchain-ai/langchain/blob/37cfc003107ea800953be912f2eebfbf069c9587/libs/core/langchain_core/runnables/history.py#L413) code expected that response from model will be in `message` field but this response is in `text` field.
Also, current implementation of lib doesn't allow to pass the complex key like `["generations"][0][0]["text"]`.

### Description
# It's impossible to use and async ChatMessageHistory with langchain-core.
The `ChatMessageHistory` class is synchronous and doesn't have an async counterpart.
This is a problem because the `RunnableWithMessageHistory` class requires a `ChatMessageHistory` object to be passed to it. This means that it's impossible to use an async ChatMessageHistory with langchain-core.
I can't find any example of how to use it. I will try to create an example of how to use `PostgresChatMessageHistory` with async mode.
There are many problems:
- Bug in `_exit_history()`
- Bugs in `PostgresChatMessageHistory` and sync usage
- Bugs in `PostgresChatMessageHistory` and async usage
## Bug in `_exit_history()`
In `RunnableWithMessageHistory`, the `_exit_history()` is called because the chain has `| runnable.with_listeners(on_end=self._exit_history)`. This method is not async and it will raise an error. This method call `add_messages()` and not `await aadd_messages()`.
```python
import asyncio
import uuid
from pprint import pprint
import psycopg
from langchain_core.chat_history import BaseChatMessageHistory
from langchain_core.prompts import ChatPromptTemplate, MessagesPlaceholder
from langchain_core.runnables.history import RunnableWithMessageHistory
from langchain_openai import ChatOpenAI
from langchain_postgres import PostgresChatMessageHistory
model = ChatOpenAI()
prompt = ChatPromptTemplate.from_messages(
[
(
"system",
"You're an assistant who's good at {ability}. Respond in 20 words or fewer",
),
MessagesPlaceholder(variable_name="history"),
("human", "{input}"),
]
)
runnable = prompt | model
table_name = "chat_history"
async_connection = None
async def init_async_connection():
global async_connection
async_connection = await psycopg.AsyncConnection.connect(
user="postgres",
password="password_postgres",
host="localhost",
port=5432)
def aget_session_history(session_id: str) -> BaseChatMessageHistory:
return PostgresChatMessageHistory(
table_name,
session_id,
async_connection=async_connection
)
awith_message_history = RunnableWithMessageHistory(
runnable,
aget_session_history,
input_messages_key="input",
history_messages_key="history",
)
async def amain():
await init_async_connection() # Glups ! It's not a global initialization
result = await awith_message_history.ainvoke(
{"ability": "math", "input": "What does cosine mean?"},
config={"configurable": {"session_id": str(uuid.uuid4())}},
)
pprint(result)
asyncio.run(amain())
```
Result
```

```
## Bugs in `PostgresChatMessageHistory` and sync usage
In `PostgresChatMessageHistory`, the design is problematic.
Langchain, with LCEL, is declarative programming. You have to declare a chain in global variables, then invoke them when necessary. This is how langserv is able to publish interfaces with `add_route()`.
For optimization reasons, `PostgresChatMessageHistory` wishes to recycle connections. The class provides a constructor which accepts a `sync_connection` parameter. However, it is not possible to have a global connection, in order to reuse it when implementing `get_session_history()`.
```python
sync_connection = psycopg.connect( # ERROR: A connection is not reentrant!
user="postgres",
password="password_postgres",
host="localhost",
port=5432)
def get_session_history(session_id: str) -> BaseChatMessageHistory:
return PostgresChatMessageHistory(
table_name,
session_id,
sync_connection=sync_connection
)
```
A connection is not reentrant! You can't use the same connection in multiple threads. But, the design of langchain-postgres is to have a global connection. This is a problem.
The alternative is to create a new connection each time you need to access the database.
```python
def get_session_history(session_id: str) -> BaseChatMessageHistory:
sync_connection = psycopg.connect( # ERROR: A connection is not reentrant!
user="postgres",
password="password_postgres",
host="localhost",
port=5432)
return PostgresChatMessageHistory(
table_name,
session_id,
sync_connection=sync_connection
)
```
Then, why accept only a connection and not an engine? The engine is a connection pool.
## Bugs in `PostgresChatMessageHistory` and async usage
If we ignore the problem mentioned above with `_exit_history()`, there are even more difficulties. It's not easy to initialize a global async connection. Because it's must be initialized in an async function.
```python
async_connection = None
async def init_async_connection(): # Where call this function?
global async_connection
async_connection = await psycopg.AsyncConnection.connect(
user="postgres",
password="password_postgres",
host="localhost",
port=5432)
```
And, it's not possible to call `init_async_connection()` in `get_session_history()`. `get_session_history()` is not async. It's a problem.
```
def get_session_history(session_id: str) -> BaseChatMessageHistory:
async_connection = await psycopg.AsyncConnection.connect( # ERROR: 'await' outside async function
user="postgres",
password="password_postgres",
host="localhost",
port=5432)
return PostgresChatMessageHistory(
table_name,
session_id,
async_connection=async_connection
)
```
It is therefore currently impossible to implement session history correctly in asynchronous mode.
Either you use a global connection, but that's not possible, or you open the connection in ̀get_session_history()`, but that's impossible.
The only solution is to completely break the use of LCEL, by building the chain just after the connection is opened. It's still very strange. To publish it with langserv, you need to use a `RunnableLambda`.
```python
async def async_lambda_history(input:Dict[str,Any],config:Dict[str,Any]):
async_connection = await psycopg.AsyncConnection.connect(
user="postgres",
password="password_postgres",
host="localhost",
port=5432)
def _get_session_history(session_id: str) -> BaseChatMessageHistory:
return PostgresChatMessageHistory(
table_name,
session_id,
async_connection=async_connection
)
awith_message_history = RunnableWithMessageHistory(
runnable,
_get_session_history,
input_messages_key="input",
history_messages_key="history",
)
result = await awith_message_history.ainvoke(
input,
config=config,
)
pprint(result)
def nope():
pass
lambda_chain=RunnableLambda(func=nope,afunc=async_lambda_history)
async def lambda_amain():
result = await lambda_chain.ainvoke(
{"ability": "math", "input": "What does cosine mean?"},
config={"configurable": {"session_id": str(uuid.uuid4())}},
)
pprint(result)
asyncio.run(lambda_amain())
```
It's a very strange way to use langchain.
But a good use of langchain in a website consists precisely in using only asynchronous approaches. This must include history management.

### Issue with current documentation:
The current import statement in the ``` qa_chat_history.ipynb ``` tutorial uses dynamic import handling via a dictionary in the ``` langchain.chains ``` module called ``` _module_lookup ```. While this works at runtime, it might affect the development experience in code editors, as developers won't navigate to ``` create_retrieval_chain ``` function on click.
### Steps to check
1. Go to the [QA Chat History tutorial](https://github.com/langchain-ai/langchain/blob/master/docs/docs/tutorials/qa_chat_history.ipynb)
2. Check the import statement: ``` from langchain.chains import create_retrieval_chain ```.
3. Attempt to navigate to `create_retrieval_chain` in the code editor.
### Expected Behavior
Developers should be able to navigate to `create_retrieval_chain` definition on click in the code editor
### Current Behavior
Developers can't navigate to ` create_retrieval_chain` on click.
### Suggested Improvement
Consider updating the import statement to:
```python
from langchain.chains.retrieval import create_retrieval_chain
```

_No response_
### Description
SelfQueryRetriever returns empty result for composite filter with query. In the above code, for example 1 - the llm returns the filter and arguments correctly. Here is the output from the llm
```
{
"output": {
"query": "toys",
"filter": {
"operator": "and",
"arguments": [
{
"comparator": "eq",
"attribute": "year",
"value": 1995
},
{
"comparator": "eq",
"attribute": "genre",
"value": "animated"
},
{
"comparator": "eq",
"attribute": "director",
"value": "Andrei Tarkovsky"
}
]
}
}
}
```
But the SelfQueryRetriever returns empty result even though the Document 5 exactly matches the filter and query. The example - 5 also is not returning the correct document. The code added here is from the langchain documentation https://python.langchain.com/v0.1/docs/integrations/retrievers/self_query/pgvector_self_query/. The only change that is made here is I have added "director": "Andrei Tarkovsky" as metadata to Document 5.

### Error Message and Stack Trace (if applicable)
_No response_
### Description
I am building a chat langchain agent powered by openai models. The agent is part of the backend of a web app that has a frontend where the user can interact with the agent.
The goal of this agent is to do some tool calling when the user message requires to do so. Some of the tools require to download images and send them to frontend so the user can visualize them. This process is done by encoding the images with base64, so that they are displayed correctly to the user.
The problem I am facing is that base64 image gets truncated when the agent finishes the chain and returns the answer. As an example, the base64 image that is downloaded by `download_image` has a length of 54443, while the answer returned by the agent has a length of 5762. This means that the image gets truncated by the agent. I am not completely sure why this happens, but maybe it is related with the maximum number of tokens that the agent can handle.
Some alternatives that I have tried, but failed to make this work:
- Reduce the image size: the image gets truncated anyway
- Reduce the image quality: the image gets truncated anyway
- Try do divide the image in chunks: works fine, but after I ask the agent to reassemble the chunks, it gets truncated.
- Reduce the `max_iteration` parameter in `AgentExecutor` but the problems persists
I guess I could get into more low level stuff and try to override some default configuration of the agent, but first I wanted to ask for help to solve this problem.

### Description
I am using **_LLMGraphTransformer_** for graph conversion.
3 weeks ago, it was worked. But today I tried again and found an error. (openai.BadRequestError: Error code: 400 - {'error': {'message': "Invalid schema for function 'DynamicGraph': None is not of type 'array'. (request id: 202405211552194421309295141805)", 'type': 'invalid_request_error', 'param': '', 'code': None}})
I've tried with others (who have also run this code successfully before) to solve the problem, but they report same error. We think some updates may caused this.

### Description
I tried to use a chain to implement the agent, but I got an error, which I initially judged to be an execution error of _tools_chain, which is the function code added later.
But this error doesn't always occur, sometimes it works fine

### Description
<img width="1676" alt="图片" src="https://github.com/langchain-ai/langchain/assets/1850771/0d9c05f0-cc2c-4b9a-8b35-878bd63fa79d">
In Langchain's React agent, there are many potential points for injection. With more and more platforms supporting the creation of custom agents, I believe these applications may face prompt injection risks. This could lead to content being tampered with, the injection of malicious third-party agents, and unintentionally invoking hacker tools that capture the privacy of users' input questions. Can I apply for a CVE for this issue?

### Example Code
This is the way it should work natually but as `RetryOutputParser` is outdated we can not use this code.
```
parser = PydanticOutputParser()
fix_parser = RetryOutputParser.from_llm(parser=parser, llm=ChatOpenAI())
structured_llm = ai_model | fix_parser
work_chain = template_obj | structured_llm
work_chain = work_chain.with_retry(stop_after_attempt=3) # type: ignore
# invoke_result: P = await work_chain.ainvoke(input_dict) # type: ignore
invoke_result: P = await work_chain.ainvoke(input_dict) # type: ignore
```
### Error Message and Stack Trace (if applicable)
_No response_
### Description
The [RetryWithError](https://python.langchain.com/v0.1/docs/modules/model_io/output_parsers/types/retry/) output parser is not integrated with LCEL. I would like to use it with the `with_retry` method but it is clearly outdated.
In my opinion it should have the `parse_result `method.

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
- [X] I am sure that this is a bug in LangChain rather than my code.
- [X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).
### Example Code
n/a
### Error Message and Stack Trace (if applicable)
_No response_
### Description
I would like to stream response tokens from an `AgentExecutor`. Based on [these docs](https://python.langchain.com/v0.1/docs/modules/agents/how_to/streaming/#custom-streaming-with-events), the default event of `stream` is different from other runnables, and to stream tokens of the response, we're expected to use `astream_events`.
My codebase is currently not async, as it doesn't need to be (running on AWS Lambda, which just processes 1 request at a time). I see that most of the standard runnable methods come in sync and async pairs:
- `invoke` and `ainvoke`
- `stream` and `astream`
etc. However, `astream_events` does not have a sync alternative `stream_events`. Is there a reason for it or was it a mistake?
