found "stream" but expected [rpc method] for a valid proto

service MyStreamService {

Hi @shreyanshp - are you expecting something different? Your example is invalid Protobuf as fas as I know. It should be:

service MyStreamService {
    rpc (stream MyStreamRequest) returns (stream MyStreamResponse);
}

Maybe I am misunderstanding the issue though, please let me know.

Going to close this, as I think it is an error in your proto file - but please re-open if that is not the case. Thanks!
