Error from server (InternalError): Internal error occurred: failed calling webhook "managedclustervalidators.admission.cluster.open-cluster-management.io": the server could not find the requested resource

         

      • This webhook does not exists anymore. The issue started when one of their admins accidentally tried removing mce with these commands:{}
      oc delete apiservice v1.admission.cluster.open-cluster-management.io v1.admission.work.open-cluster-management.io
oc delete validatingwebhookconfiguration multiclusterengines.multicluster.openshift.io
oc delete mce --all{{}}
