gRPC 0 OK vs 3 INVALID_ARGUMENT
Both gRPC 0 (OK) and 3 (INVALID_ARGUMENT) belong to the gRPC Status Codes category. 0 indicates that the operation completed successfully. Not an error; returned on success. Meanwhile, 3 means that the client specified an invalid argument. This indicates arguments that are problematic regardless of the state of the system.
