      The following test is failing:

      [sig-api-machinery] ValidatingAdmissionPolicy [Privileged:ClusterAdmin] should type check a CRD [Suite:openshift/conformance/parallel] [Suite:k8s]

      Additional context here:

      This was a problem back in 4.16 when the test had Beta in the name. https://issues.redhat.com/browse/OCPBUGS-30767

      But the test continues to be quite flaky and we just got unlucky and failed a payload on it.

      The failure always seems to be:

      {  fail [k8s.io/kubernetes/test/e2e/apimachinery/validatingadmissionpolicy.go:380]: wait for type checking: PatchOptions.meta.k8s.io "" is invalid: fieldManager: Required value: is required for apply patch
      Error: exit with code 1
      Ginkgo exit error 1: exit with code 1}
      

      See: https://prow.ci.openshift.org/view/gs/test-platform-results/logs/periodic-ci-openshift-multiarch-master-nightly-4.18-ocp-e2e-gcp-ovn-multi-x-ax/1828347537950511104

      It often works on a re-try. (flakes)

      Something is not quite right either with this test or the product.
