[Bug] index.list() error message for non-serverless indexes is unclear

[shamussim-ai]

Is this a new bug in the Pinecone Python client?

• [X] I believe this is a new bug in the Pinecone Python Client
• [X] I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

I followed the code exactly from the documentation

from pinecone import Pinecone

pc = Pinecone(api_key='34zzzzzzzzzz')
index = pc.Index('self-retriever-pae')

# To iterate over all result pages using a generator function
for ids in index.list( namespace="Non_Varicea"):
    print(ids)

This succeeds (as expected) against a serverless index, but when run on a pod-based index (which indeed does not support list()) an unclear error message is returned:

PineconeApiTypeError: Invalid type for variable 'received_data'. Required value type is ListResponse and passed type was str at ['received_data']

Expected Behavior

When run on a non-serverless index (which do not support list()) a clear error message that this is an unsupported operation should be displayed.

Steps To Reproduce

Run code using env specified

Code

from pinecone import Pinecone

pc = Pinecone(api_key='34zzzzzzzzzz')
index = pc.Index('self-retriever-pae')

# To iterate over all result pages using a generator function
for ids in index.list( namespace="Non_Varicea"):
    print(ids)

Relevant log output

Can confirm this is also an issue for us

Hi there, any updates on this? Thank you

I attempted to reproduce this on the latest version (v4.0.0) on macOS and don't see the problem anymore.

@daverigby I finally figured out why this was not working. This only works for a serverless index. The error message could probably be clearer.

Thanks @cbelsole . I'll re-open and change to cover the fact that the error is not clear for non-server less indexes.
