minikube: Ingress addon: `Error: server.go:84] "failed to process webhook request" err="rejecting admission review because the request does not contain an Ingress resource but networking.k8s.io/v1, Kind=Ingress with name`

Steps to reproduce the issue:

Minikube v1.19.0 docker driver on PopOS 20.10

Using the ingress plugin, installing an ingress always fails.

Exact same steps and yaml works in v1.18.1

Doesn’t matter if the ingress is defined with apiVersion: networking.k8s.io/v1 or apiVersion: extensions/v1beta1 (yaml files used to test each work in v1.18.1)

Suspect that ansible/awx-operator#205 is the same issue.

Failing ingress definition:

- apiVersion: networking.k8s.io/v1
  kind: Ingress
