EnvoyFilter gives "spec.configPatches.match.listener: Required value" error for everything

Config

Hi,

I’m trying to add an EnvoyFilter. Although i provided the required “routeConfiguration” object under “configPatches.match”, i still got the below error.

“Invalid value: “”: “spec.configPatches.match” must validate one and only one schema (oneOf). Found none valid.”
“spec.configPatches.match.listener: Required value”

according to the docs, it can be either listener, route configuration, or cluster. https://istio.io/docs/reference/config/networking/envoy-filter/#EnvoyFilter-EnvoyConfigObjectMatch

I’m basically stuck :slightly_smiling_face: Any help will be appreciated, thanks
Erkan

Hey @Erkan_Durmaz,

on your second applyTo you use a match, but don’t offer a required field, such as a listener:

- applyTo: CLUSTER
 match:
  context: SIDECAR_INBOUND
->here you are missing listener:
patch:
  operation: ADD

thanks @Eneminemoe :+1:

I managed to make it work using a cluster object instead of a listener

   - applyTo: CLUSTER
      match:
        context: SIDECAR_INBOUND
        cluster:
            name: cache-agent
      patch:
        operation: ADD
        value: 
          name: cache-agent
          type: STATIC
          connect_timeout: 0.5s
