Error message

{exception_provider} - {message}

 This error occurs when load balancing Responses API across deployments with different API keys.
   Encrypted content is tied to the organization that created it and cannot be decrypted by other organizations.

   Solution: Enable 'encrypted_content_affinity' to route follow-up requests to the correct deployment:

   router_settings:
     enable_pre_call_checks: true
     optional_pre_call_checks:
       - encrypted_content_affinity
