Unimplemented desc = unknown service workflow.Workflow.

Im using dtm-labs/client/workflow packaged to register gRPC workflow server in following way:

import (
	"github.com/dtm-labs/client/dtmcli"
	"github.com/dtm-labs/client/dtmgrpc/dtmgimp"
	"github.com/dtm-labs/client/workflow"
        ...
)

...

func InitDtmGrpc(grpcDtm string, host string, port int) {
	lis, err := net.Listen("tcp", fmt.Sprintf(":%d", port))
	if err != nil {
		log.Fatal(err)
	}

	server := grpc.NewServer(grpc.UnaryInterceptor(dtmgimp.GrpcServerLog))
	workflow.InitGrpc(grpcDtm, fmt.Sprintf("%s:%d", host, port), server)
	go func() {
		if err := server.Serve(lis); err != nil {
			log.Fatal(err)
		}
	}()
}

But the DTM which calls the workflow server can't find the service as if it was unregistered.

I've checked the ports and connection and it seems to be fine, it's just that workflow service doesn't seem to be registered for some reason
