kubernetes: Dynamic storage is unavailable due to the removal of SelfLink

What happened: I am seeing the issue that since installing the latest version (v1.20.1) I have the problem that my ‘testclaim’ pvc is no longer able to claim storage from the storageclass (managed-nfs-storage), which worked fine before 1.20.1

What you expected to happen: I want to be able to use dynamic storage，such as NFS, OpenEBS

How to reproduce it (as minimally and precisely as possible):

Apply the example custom resource definition from the sample controller project:

kubectl apply -f https://github.com/kubernetes-retired/external-storage/blob/master/nfs-client/deploy/deployment.yaml

kubectl logs -f nfs-client-provisioner-64597768d6-7jws4 I1223 07:26:44.544567 1 leaderelection.go:185] attempting to acquire leader lease default/fuseim.pri-ifs… E1223 07:27:01.969864 1 event.go:259] Could not construct reference to: ‘&v1.Endpoints{TypeMeta:v1.TypeMeta{Kind:“”, APIVersion:“”}, ObjectMeta:v1.ObjectMeta{Name:“fuseim.pri-ifs”, GenerateName:“”, Namespace:“default”, SelfLink:“”, UID:“b5a42eb2-9b14-4ab8-9114-c5e625cfe73a”, ResourceVersion:“164217”, Generation:0, CreationTimestamp:v1.Time{Time:time.Time{wall:0x0, ext:63744226452, loc:(*time.Location)(0x1956800)}}, DeletionTimestamp:(*v1.Time)(nil), DeletionGracePeriodSeconds:(*int64)(nil), Labels:map[string]string(nil), Annotations:map[string]string{“control-plane.alpha.kubernetes.io/leader”:“{"holderIdentity":"nfs-client-provisioner-64597768d6-7jws4_3581561e-44f0-11eb-8f64-0e9e382e10fd","leaseDurationSeconds":15,"acquireTime":"2020-12-23T07:27:01Z","renewTime":"2020-12-23T07:27:01Z","leaderTransitions":5}”}, OwnerReferences:[]v1.OwnerReference(nil), Initializers:(*v1.Initializers)(nil), Finalizers:[]string(nil), ClusterName:“”}, Subsets:[]v1.EndpointSubset(nil)}’ due to: ‘selfLink was empty, can’t make reference’.
