Deviation from expected behavior: Errors in csi-rbdplugin-provisioner log:

E0813 11:41:22.198321       1 reflector.go:156] github.com/kubernetes-csi/external-snapshotter/pkg/client/informers/externalversions/factory.go:117: Failed to list *v1beta1.VolumeSnapshotContent: the server could not find the requested resource (get volumesnapshotcontents.snapshot.storage.k8s.io)

Expected behavior: No errors in csi-rbdplugin-provisioner log How to reproduce it (minimal and precise): Just upgrade v1.3.9 to v1.4.x

File(s) to submit:

• Cluster CR (custom resource), typically called cluster.yaml, if necessary
• Operator’s logs, if necessary
• Crashing pod(s) logs, if necessary

To get logs, use kubectl -n <namespace> logs <pod name> When pasting logs, always surround them with backticks or use the insert code button from the Github UI. Read Github documentation if you need help.
