KeyError

At a glance

The post describes an issue with a chat_engine object, where a KeyError is raised due to the absence of a custom_chat_history parameter. Community members suggest changing custom_chat_history to chat_history to resolve the issue. However, the code still does not seem to respond as expected, and the community members discuss potential debugging approaches, such as using a debugger, though the original poster acknowledges their limited experience with Python.

Plain Text

chat_engine = CondenseQuestionChatEngine.from_defaults(
    query_engine=index.as_query_engine(),
    condense_question_prompt=custom_prompt,
    chat_history=custom_chat_history,
    verbose=True,
    llm=llm,
    service_context=service_context,
)

Gives me

Welp it does reply, just needs way to long for just giving a "Dunno"

Heya @Logan M do you know what that would happen?

LLogan M

I have no idea unfortunately -- I would have to walk through code with a debugger to figure it out (and that is an option I highly recommend getting good at with python tbh)

TTay

Sorry to ask so stupidly, but how do I do that? I'm very much not good with python, as you can probably tell

TTay

@Logan M hehe
