Describe the bug
The delete function in the Pinecone Vector Store raises an AttributeError when running on Google Cloud Run. The error occurs inside the tenacity retry mechanism due to self.index.list() unexpectedly returning a str instead of the expected response format containing the vectors attribute. This error only appears in production on Google Cloud Run, while the same operation works successfully locally on a Fedora Linux environment.

Steps to reproduce the issue locally

1. Deploy the code to a Google Cloud Run environment.
2. Attempt to delete entries from the Pinecone Vector Store using the delete function.
3. Observe that the retry mechanism raises an AttributeError due to the unexpected str response from self.index.list().

Environment

• OS Version: Fedora Linux (local), Google Cloud Run (production)
• Python version: 3.10
• Pinecone SDK version: ^5.3.1
• Tenacity version: 8.2.3

Additional context
This issue may also affect other vector store functions that rely on self.index.list().
