What is the version of your installed websockets package?

pip list | grep websockets

[pors]

It is probably incompatibility between websockets and python 3.11. I only tested this with Python 3.10.9

[janfilips]

I'll play around with this and come back here with my findings

[janfilips]

Python 3.11.4

[janfilips]

It is slightly outdated, I guess these things move quickly, including the langchain, e.g. as far as I know it no longer supports ConversationChain as an example.
