THEN Upgrade LangChain to a version after October 2023 that includes a fix for this known bug. Alternatively, wrap the streaming chain call in a try-except for openai.error.APIError and ignore the exception if the response was already successfully streamed to avoid breaking the application.

try:
    response = chain.run(input_documents=docs, **inputs)
except openai.error.APIError as e:
    if hasattr(e, 'http_status') and e.http_status == 200:
        # Ignore final error on successful streaming
        pass
    else:
        raise
