gRPC 3 INVALID_ARGUMENT vs 7 PERMISSION_DENIED
Both gRPC 3 (INVALID_ARGUMENT) and 7 (PERMISSION_DENIED) belong to the gRPC Status Codes category. 3 indicates that the client specified an invalid argument. This indicates arguments that are problematic regardless of the state of the system. Meanwhile, 7 means that the caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead.
