Why am I seeing this error from a file in the pinecone-client library when running my code? I saw that the chain runs properly on its own, the only problem seems to be its integration in the streamlit app, but why is that?

That ‘NoneType’ error generally occurs when there is no instance of the class you’re calling- pinecone.init likely failed. It looks like you may be missing a `"` in `environment="gcp-free"` - try it out and let me know if that’s not the case.

I figured out eventually that what I was missing was storing the Pinecone API key and environment in the streamlit cache. So that one was actually on Streamlit. But thanks for the help!
