Unable to use "type.googleapis.com/google.protobuf.StringValue" in Matcher_OnMatch.Matcher_OnMatch_Action.TypedExtensionConfig.TypedConfig. TypeUrl: "type.googleapis.com/google.protobuf.StringValue",

[lmq1999]

I follow the example on:
https://www.envoyproxy.io/docs/envoy/latest/start/sandboxes/dynamic-config-cp for coding the new CP for my usecase

This is my envoy.yaml and it working perfectly on version 1.32.2: https://pikab.in/ae8aec158a [1]
This is the code to create the CP for my file above: https://pikab.in/89d41d2b23 [2]

(I only change the resource.go in https://github.com/envoyproxy/examples/blob/main/dynamic-config-cp/resource.go with my new resource.go file above in [2])

But I got these error:

I don't know where I was wrong and the control-plane is not working

[valerian-roche]

Hey, this seems like an issue in the way resources are built prior to being provided to the go-control-plane cache.
From the snippet you linked this seems invalid as this is not how a string would be serialized:

TypedConfig: &anypb.Any{
  TypeUrl: "type.googleapis.com/google.protobuf.StringValue",
  Value:   []byte("filter_nginx_0"),
},
