TypeError: string indices must be integers

Nobody has claimed this yet.

Use the Python openai to call the FastChat API + baichuan2-13B, then I received the "TypeError: string indices must be integers" error

The full error message:
"""
Traceback (most recent call last):
File "C:\Users\Adams\anaconda3\lib\site-packages\openai\api_requestor.py", line 413, in handle_error_response
error_data = resp["error"]

During handling of the above exception, another exception occurred:

The report points to the Python openai.Completion.create call and api_requestor.py while using the FastChat API with baichuan2-13B, but names no FastChat repository file or test. Start by reproducing the request and inspect the response handling around the reported error; done would mean the failure is diagnosed and produces a correctly handled API error instead of the TypeError.
