Error:Unrecognized request argument supplied: functions

[runningcd]

Mycode:

def main():
    with CodeInterpreterSession() as session:

        response = session.generate_response_sync(
            f"Plot the bitcoin chart of 2023 YTD ",
            detailed_error = True
        )

        # prints the text and shows the image
        response.show()

Then I get the Error: AI: Error in CodeInterpreterSession: InvalidRequestError - Unrecognized request argument supplied: functions

how to get a llm that supports using functions.
