Envoy 1.23.0-dev Didn't find a registered implementation for 'envoy.filters.http.router' with type URL: ''

Title: Envoy 1.23.0-dev Didn't find a registered implementation for 'envoy.filters.http.router' with type URL: ''

Description:
I am investigating Envoy external processing filter by following the setup in https://github.com/salrashid123/envoy_ext_proc. My envoy version is:

cd7ea77/1.23.0-dev/Clean/RELEASE/BoringSSL

When I run the following command to validate Envoy configuration, it complains: Didn't find a registered implementation for 'envoy.filters.http.router' with type URL: ''

envoy --mode validate -c server.yaml

The server.yaml is in https://github.com/salrashid123/envoy_ext_proc/blob/main/server.yaml

Seems like the example you are following is not up to date with current configuration

Where you currently have:

         - name: envoy.filters.http.router

You need:

         - name: envoy.filters.http.router
           typed_config:
             "@type": type.googleapis.com/envoy.extensions.filters.http.router.v3.Router

@phlax thanks for your kindly help! It works after I add typed_config to the server.yaml.

Thankyou very helpful, already balanced with quota 50/50 :)
