Is this contained in release 3.3.0? With this deployed I still get

Error presenting challenge: admission webhook "validate.nginx.ingress.kubernetes.io" denied the request: rejecting admission review because the request does not contains an Ingress resource but networking.k8s.io/v1, Resource=ingresses with name cm-acme-http-solver-kxggk in namespace testnamespace

on kubectl describe challenge -A (using cert-manager).

@haslersn no, this change is not released yet. This requires a release of the ingress controller and then a helm chart update

[haslersn]

For the naive me it looks like this is released because it's in the branch ingress-nginx-3.3.0. Is there a workaround in order to already get this change?
