I am having trouble egetting through with gRPC from external to istio-ingress on Kubernetes.

But I have come so fare, that I can get a respons 200. Now I expect that HTTP/1.1 is curl not supporting http2.

Any help is appreciated, thanks!

HTTP/1.1 200 OK
content-type: application/grpc
grpc-status: 8
grpc-message: malformed method name: "/ghw"
x-envoy-upstream-service-time: 8
