Problem in Integrating Langchain RunnableWithMessageHistory about nemo-guardrails

[drazvan]

This is a bug. The config parameter is not used properly. It needs to be fixed. Contributions are welcomed here!

Hi @nikithakriz have you checked this doc from langchain on using session id https://github.com/langchain-ai/langchain/blob/master/docs/docs/integrations/memory/mongodb_chat_message_history.ipynb . chat_history for session_id requires "session_id":

chain_with_history = RunnableWithMessageHistory(
    chain,
    lambda session_id: MongoDBChatMessageHistory(
        session_id=session_id,
        connection_string="mongodb://mongo_user:password123@mongo:27017",
        database_name="my_db",
        collection_name="chat_histories",
    ),
    input_messages_key="question",
    history_messages_key="history",
)

I am able to create chain with chat history without nemoguardrails, the error raising when integrating with nemoguardrails
