Hello all. Not sure if this is an issue with the envoy proxy but I am using Istio 1.6.5 with grpc-web and I noticed that every single request made using grpc-web is reported with a status code of 2 (UNKNOWN) despite the request working completely normally. When I make via grpc the metrics are reported with the real status code of 0 (OK).
I first noticed this issue when we started building grafana dashboards on these metrics.
Below is traffic starting with grpc-web, followed by requests made by grpc.
