You could match on various PDF files (i.e. invoice, receipt, or contract).\\n4.

By listening instead of reading, users can soak in the info in a fun and easy way.\n\nThis project rocks a workflow using n8n to automate tasks like a boss. Each node in the workflow plays its part in a smooth operation. Check out the main players:\n\n1. **Gmail trigger1 Node**: Kicks off the action every minute for those \"CATEGORY_PROMOTIONS\" emails.\n   \n2. **Get message content1 Node**: Grabs the email content for some magic.\n      \n3. **Summarization Chain3 Node**: Whips up some sweet summaries using fancy chunking methods.\n   \n4. **Delete the unnecessary items Node**: Clears out the clutter from the email content.\n   \n5. **Text to Free TTS Node**: Turns the summary into speech using Free TTS magic.\n   \n6. **Convert from base64 to File Node**: Changes the audio into a file format.\n   \n7. **Merge Text with Audio Node**: Mixes the text and audio together for a cool combo.\n   \n8. **Aggregate in same cell Node**: Puts all the data together for more awesomeness.\n   \n10. **Send Message to Telegram Node**: Sends the final audio message with a caption to a special Telegram chat ID.\n\nThis workflow is like a well-oiled machine, with each step flowing seamlessly into the next. By automating these tasks, this project aims to make communication a breeze and bring joy to all involved! \ud83c\udf08\u2728\ud83d\ude80\n`\n\n**Root Cause**: The expression references a field, node, or variable that doesn't exist in the data flow.\n\n**Debugging Steps**:\n1. Check the output of previous nodes to verify available fields\n2. Use the Expression Editor to test expressions interactively\n3. Add a Set node before this one to inspect available data\n4. Use optional chaining for potentially undefined fields: `$json.field?.subfield`\n\n**Best Practice**: Always validate data availability before using expressions.", "metadata": {"error_type": "Expression Reference Error", "fix_hint": "Fix the expression in 'Sticky Note' parameter 'content'.", "type": "debugging"}}

The steps are as follows:\\n\\n1. **Notion Page Added Trigger**:\\n - Monitors a specified Notion database for newly added pages. You can create a specific Notion database where you copy the pages you want to store in Supabase.\\n - Node: `Page Added in Notion Database`\\n\\n2. **Retrieve Page Content**:\\n - Fetches all block content from the newly added Notion page.\\n - Node: `Get Blocks Content`\\n\\n3. **Filter Non-Text Content**:\\n - Excludes blocks of type \\\"image\\\" and \\\"video\\\" to focus on textual content.\\n - Node: `Filter - Exclude Media Content`\\n\\n4. **Summarize Content**:\\n - Concatenates the Notion blocks content to create a single text for embedding.\\n - Node: `Summarize - Concatenate Notion's blocks content`\\n\\n5. **Store in Supabase**:\\n - Stores the processed documents and their embeddings into a Supabase table with a vector column.\\n - Node: `Store Documents in Supabase`\\n\\n6. **Generate Embeddings**:\\n - Utilizes OpenAI's API to generate embeddings f...", "input": "", "output": "The node 'Notion - Page Added Trigger' has a data type mismatch in its parameters.\n\n**Issue**: A field expected a number but received a string value.\n\n**Common Causes**:\n1.
