…andling When the delete endpoint returns a response that deserializes to a primitive type (e.g. str), the code tried to call setattr() on it to attach _response_info, which raises AttributeError since primitive types do not support arbitrary attribute assignment. Add a hasattr(__dict__) check before setattr to only attach response info on objects that support dynamic attributes (OpenAPI models). Primitive return types silently skip the response info attachment. Fixes pinecone-io#564

Summary
Fixes #564. When calling
await index.delete()via the asyncio SDK, the response deserializes to a primitive type (e.g.str), and the subsequentsetattr(return_data, "_response_info", response_info)raisesAttributeError: 'str' object has no attribute '_response_info'because primitive types do not support arbitrary attribute assignment.This PR adds a
hasattr(return_data, "__dict__")guard before callingsetattr, so response info is only attached to objects that support dynamic attribute assignment (i.e. OpenAPI model instances). For primitive return types (str,int,float,bool), the response info attachment is silently skipped.The fix is applied to both the async client (
asyncio_api_client.py) and the sync client (api_client.py) since both contain the same vulnerable code path.Changes
pinecone/openapi_support/asyncio_api_client.py: Replace bareelsewithelif hasattr(return_data, "__dict__")beforesetattrcallpinecone/openapi_support/api_client.py: Same fix applied to the sync client for consistencyReproduction
The bug occurs when using pinecone-local:
After this fix, the delete call completes without error.

Note
Low Risk
Small, localized defensive change in client response handling; behavior only differs for primitive response types where metadata attachment is now skipped instead of raising.
Overview
Prevents crashes when an endpoint deserializes to a primitive (e.g.,
str) by only attaching_response_infowhen the return value is adictor supports dynamic attributes (has__dict__).Applies the same guard in both
api_client.py(sync) andasyncio_api_client.py(async), leaving primitive responses unchanged while still enriching OpenAPI model objects with response metadata.Written by Cursor Bugbot for commit 35c6b9e. This will update automatically on new commits. Configure here.
