CTX: Session Migration [781d0d -> 80a60b]
MSG: Found AIMessages with tool_calls that do not have a corresponding ToolMessage. Here are the first few of those tool calls: [{'name': 'load_scopus_csv', 'args': {'file_path': 'scopus_data.csv'}, 'id': 'JrfgG54k6', 'type': 'tool_call'}].

Every tool call (LLM requesting to call a tool) in the message history MUST have a corresponding ToolMessage (result of a tool invocation to return to the LLM) - this is required by most LLM providers.
