AdmissionResponse.Warnings do not show warning

[Tiger20111]

Hello!

I have a working validator on the Openschift and Kubernetis clusters. Then I wanted to add warnings.

As example:

1. admissionReview.Response.Warnings = append(admissionReview.Response.Warnings, "Test element")
2. return &v1beta1.AdmissionResponse{
   Allowed: true,
   Warnings: []string{"Test"},
   }

From the container side, the response goes away with warning, but no warning appears either in the terminal or in the interface.

Kubernetes Version: v1.19.0+9c69bdc

I did everything according to:

1. https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/
2. https://github.com/kubernetes/api/blob/master/admission/v1beta1/types.go

Can you help with this?

I installed oc-cli with version 4.6. This solved my problem.
