Steps to reproduce this issue

Consumer get an exception with grc-status:13(INTERNAL) when provider return "Mono.empty()" in reactive rpc;

What you expected to happen

Consumer should get exception with grc-status:5 and detail ： NOT_FOUND.

why the method "org.apache.dubbo.rpc.protocol.tri.h12.grpc.GrpcHttp2ServerTransportListener#httpStatusToGrpcStatus" always return 13 ？
