Fix PineconeApiException

✅ Solution

PineconeApiException usually stems from malformed requests to the Pinecone service, often due to incorrect data types or improperly formatted filter expressions in your queries, upserts, or deletes. Review your code, especially your metadata filters and vector data structures, to ensure they conform to Pinecone's API requirements (e.g., correct types for metadata values, valid JSON syntax for filters). Use Pinecone's debug logging to inspect the exact request being sent and correlate it with the API documentation for the endpoint you are using to identify the mismatch.
