Fix BadRequestError

✅ Solution

BadRequestError in Langchain usually arises from improperly formatted requests sent to a language model, such as incorrect tool inputs or file types. To resolve it, carefully inspect the request payload for data type mismatches or violations of the API's expected schema, ensuring all data conforms to the specified format (e.g., correct file MIME types, proper tool input structures). Validate your inputs against the LLM provider's API documentation and example requests to identify and correct any discrepancies.
