Describe the bug
When using PineconeDocumentStore with run_async , unclosed aiohttp client session and connector errors occur during embedding_retrieval . This seems to stem from not using the IndexAsyncio client within an async context manager, as recommended by Pinecone.

Suggested Fix
Using IndexAsyncio inside an async with context (as shown in the user workaround) resolves the issue.
