Now, I’m developing grpc-server using armeria and kroto-plus. I don’t use the gRPC-Web function, but Unframed requests (for Documentation service) works well.

Are you using the Coroutines generation by any chance? Unary requests worked fine for me. But server streaming when wrapped in Armeria doesn't seem to work. Did you encounter anything like that?

mm, actually I’m using only unary calls…
