IndexError: list index out of range

[jybaek]

I am encountering an issue while using the google.generativeai.chat library. Whenever I input the phrase "who are you?" as a message, it consistently triggers an error. This behavior seems unexpected and needs to be addressed.

response = palm.chat(messages=["who are you?"])
# error
  ...
  File "/Users/jybaek/work/xxxx/.venv/lib/python3.8/site-packages/google/generativeai/discuss.py", line 413, in reply
    return _generate_response(request=request, client=self._client)
  File "/Users/jybaek/work/xxxx/.venv/lib/python3.8/site-packages/google/generativeai/discuss.py", line 461, in _generate_response
    return _build_chat_response(request, response, client)
  File "/Users/jybaek/work/xxxx/.venv/lib/python3.8/site-packages/google/generativeai/discuss.py", line 443, in _build_chat_response
    request["messages"].append(response["candidates"][0])
IndexError: list index out of range

Is it a known issue? Please check.

I think you're using an older version of the client, Instead of "List index out of range" this now returns None.
That itself is not helpful.

The API is not returning any candidates for this request:

curl -H 'Content-Type: application/json'        \
    -H "x-goog-api-key: ${PALM_API_KEY}"      \
    -d '{"prompt": {"messages": [{"content": "who are you", "author":"0"}]}}'     \
    "https://generativelanguage.googleapis.com/v1beta2/models/chat-bison-001:generateMessage"

{
  "messages": [
    {
      "author": "0",
      "content": "who are you"
    }
  ],
  "filters": [
    {
      "reason": "OTHER"
    }
  ]
}

The owners are aware of the problem.

I found the cause. I was using Python 3.8. When installing google-generativeai with pip install in Python 3.8, it installs rc1.

Thank you for your help :)

Yeah, I think we've yanked those versions, so you shouldn't see them anymore.
