AuthorizationPolicy does not appear to work with gateway HTTPRoute's

Linkerd General Discussion
1

Linkerd states that both policy.linkerd.io and gateway.networking.k8s.io HTTPRoutes can be used under the AuthorizationPolicy documentation.

We have a working configuration for policy.linkerd.io`` HTTPRoute, but not gateway, where the AuthorizationPolicy seems to completely ignore them. We’re not seeing any errors, but we’re also not seeing any auth behaviour.

Can anyone clarify if gateway HTTPRoutes are supported for AuthorizationPolicy’s? And if so can they advise how we can debug why they’re not working?

For context, we’re on the latest edge release (at time of writing).

httproute.gateway.networking.k8s.io should absolutely work for AuthorizationPolicy, though I think it needs an HTTPRoute that ultimately targets a Server. Can you show a representative Route and AuthorizationPolicy?
