[soulxu]

This is due to https://www.envoyproxy.io/docs/envoy/latest/version_history/v1.22.0#minor-behavior-changes

config: type URL is used to lookup extensions regardless of the name field. This may cause problems for empty filter configurations or mis-matched protobuf as the typed configurations. This behavioral change can be temporarily reverted by setting runtime guard envoy.reloadable_features.no_extension_lookup_by_name to false.

You should write router filter as below:

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

or set envoy.reloadable_features.no_extension_lookup_by_name as false

[zackzhangkai]

Thanks for your replying. It works.

[iheng]

@soulxu, @zackzhangkai had same issue with version 1.23.1. with

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

it's not working. how we suppose to set envoy.reloadable_features.no_extension_lookup_by_name as false. I'm running as docker container

[phlax]

im wondering where the confusion is coming from here - checking the docs and it seems they are correct

@iheng you would be better to just get the typed_config working - the example config in examples/fault-injection/envoy.yaml should work i believe

@soulxu, @zackzhangkai had same issue with version 1.23.1. with

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

it's not working. how we suppose to set envoy.reloadable_features.no_extension_lookup_by_name as false. I'm running as docker container

I'm also using 1.23.1 and needed all 3 of the type_configs in this comment.

Also consider running your envoy.yaml through this.

[phlax]

are there any current Envoy docs that suggest running without the typed_config ?

perhaps the source of confusion is from 3rd party sites showing old config - if not i would like to update our docs
