Describe the bug
After getting the client object using our API Key, using client.list_indexes() returns an odd error.

Error information

pinecone.core.client.exceptions.PineconeApiTypeError: 
Invalid type for variable 'dimension'. 
Required value type is int and passed type was NoneType at ['received_data']['indexes'][1]['dimension']

Steps to reproduce the issue locally

import os
from pinecone import Pinecone

pc = Pinecone(api_key=os.environ.get("PINE_API_KEY"))
pc.list_indexes()

Environment

• OS Version: Sequoia 15.2
• Python version: 3.11.3
• Python SDK version: 4.1.2

Additional context
This post suggests it could be a pod vs serverless issue, but the error message is really strange. If this is the case, the message should reflect that better.

Hitting the API directly seems to work:

curl -i -X GET "https://api.pinecone.io/indexes" \
-H "Api-Key: $PINECONE_API_KEY" \
-H "X-Pinecone-API-Version: 2024-10"
