gRPC 3 INVALID_ARGUMENT vs 12 UNIMPLEMENTED
Both gRPC 3 (INVALID_ARGUMENT) and 12 (UNIMPLEMENTED) 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, 12 means that the operation is not implemented or is not supported/enabled in this service.

このコードが表示される場合

解決方法
Verify the server version supports the method you're calling. Update the server to implement the missing method, or use an alternative endpoint.
