I'm running Istio on Google Kubenetes Engine. I've been following this post to enable gRPC-web in Istio. I want to view the config of my Istio Envoy proxy to check that envoy.grpc_web is in it, but it gives me an error:

$ kubectl get pods -n rev79

NAME                               READY   STATUS    RESTARTS   AGE
rev79-deployment-8d985d775-jx6v4   3/3     Running   1          16h

$ istioctl proxy-config listeners rev79-deployment-8d985d775-jx6v4.rev79

Error: error unmarshalling config dump response from Envoy: json: cannot unmarshal object into Go value of type []json.RawMessage

How can I resolve this error?
