You say in the doc that you are passing a tuple for the history in the custom_chat_history , hence the chat_history variable in the chat_engine = CondenseQuestionChatEngine.from_defaults() ask for a dictionnary.

Yep, just checked failing for me too. Made it running by changing the way messages were added in chathistory list

Plain Text

custom_chat_history = [
    {"role":"system","content":"THis is system msg"},
]

This will make it run

You can use these roles if you want to have some initial convo

Plain Text

class MessageRole(str, Enum):
    """Message role."""

    SYSTEM = "system"
    USER = "user"
    ASSISTANT = "assistant"
    FUNCTION = "function"

maybe the docs are not updated 🧐

Looks like this slipped by yup

The docs are detailing an old/initial way of doing it before we had a defined structure

Will update this!
