gRPC 0 OK vs 7 PERMISSION_DENIED
Both gRPC 0 (OK) and 7 (PERMISSION_DENIED) belong to the gRPC Status Codes category. 0 indicates that the operation completed successfully. Not an error; returned on success. Meanwhile, 7 means that the caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead.
