Hey @KBB99! Great to see you back here in the LangChain repo. Looks like you've caught another quite interesting bug. Let's dive into this together, shall we?
Based on the information provided, it seems like the issue might be related to the CallbackManager
in the AmazonKnowledgeBasesRetriever
class. The CallbackManager
is used to handle various events that occur during the execution of the language model. It's designed to manage and handle callbacks from LangChain.
However, without the complete code of AmazonKnowledgeBasesRetriever
, it's hard to pinpoint the exact issue. The error stack trace you provided indicates that the issue might be related to logging, as the error seems to occur when the CallbackManager
tries to log a warning message.
One possible reason could be that the CallbackManager
is not properly configured, or there might be an issue with the logging configuration in your environment. It's also possible that there's a bug in the CallbackManager
or AmazonKnowledgeBasesRetriever
class that's causing this issue.
To further investigate this issue, could you please provide the complete code of the AmazonKnowledgeBasesRetriever
class and the configuration of your CallbackManager
? This would help in identifying the exact cause of the issue.
Also, could you please provide more details about the error? For example, what is the exact error message? Does the error occur every time you run the code, or only under certain conditions? Any additional information would be helpful.
As for your question about why the CallbackManager
is used in the AmazonKnowledgeBasesRetriever
, it's used to handle events specific to that component. For example, if the AmazonKnowledgeBasesRetriever
generates an event when it starts retrieving data, the CallbackManager
would call the appropriate event handler to handle this event.
I hope this helps! If you have any more questions, feel free to ask.
Best regards, Dosu

@dosu-bot When I set LANGCHAIN_TRACING_V2 to false it works. So it must be an issue with the way responses are being processed by Langsmith tracing.

Based on the information provided, it seems like the issue you're encountering is related to the CallbackManager
in the LangChain codebase. The CallbackManager
is responsible for handling various events that occur during the execution of the language models. It provides a way to define custom behavior when these events occur, such as when a language model starts running, generates a new token, ends running, or encounters an error.
However, the provided context does not include any direct interaction between the CallbackManager
and the AmazonKnowledgeBasesRetriever
, so it's not possible to provide a detailed explanation of their interaction.
The error message you provided suggests that the issue might be related to the logging system. The CallbackManager
uses Python's built-in logging module to log warnings and errors. The error message indicates that an error occurred while formatting a log message. This could be due to a problem with the log message itself (for example, if it contains a format specifier like %s
but the corresponding argument is not provided), or with the logging configuration.
You mentioned that setting LANGCHAIN_TRACING_V2
to false resolves the issue. This suggests that the problem might be related to the tracing functionality in LangChain. Tracing is a technique used to monitor the execution of an application, which can be useful for debugging and performance optimization. It's possible that there's a bug in the tracing code that's causing this issue.
Unfortunately, without more information, it's difficult to determine the exact cause of the problem. If you could provide more details about the error, such as the full error message and stack trace, it would be easier to diagnose the issue. Additionally, if you could share the code that you're using to initialize and configure the CallbackManager
and the AmazonKnowledgeBasesRetriever
, it might help to identify any potential issues with the way they're being used.
For more information about the CallbackManager
and its methods, you can refer to the LangChain codebase.

Error is a bit misleading. Turns out it was failing, because I was missing the LANGCHAIN_API_KEY in environment variables.
