trident: Creating volumesnapshot causes error status.restoreSize in body should be greater than or equal to 0

Describe the bug

I am setting up snapshots on a openshift cluster so I have created a snapshotclass

apiVersion: snapshot.storage.k8s.io/v1
kind: VolumeSnapshotClass
metadata:
  name: nap-snapshots
driver: csi.trident.netapp.io
deletionPolicy: Delete

And a volumesnapshot:

apiVersion: snapshot.storage.k8s.io/v1
kind: VolumeSnapshot
metadata:
  name: nap-nfs-pre-dr03-volym-pvc-snapshot-20210920-2
spec:
  volumeSnapshotClassName: nap-snapshots
  source:
    persistentVolumeClaimName: nap-nfs-pre-dr03-volym-pvc

However the volumesnapshot isnt created:

$ oc get volumesnapshots

tridentctl logs gives me:

The PVC is created with a storageclass defined as:

allowVolumeExpansion: true
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  creationTimestamp: "2021-05-31T08:35:55Z"

  uid: 0b365406-7fd9-47d2-9a4f-978b9d5ecf67
parameters:
  backendType: ontap-nas
  clones: "true"
  media: hybrid
  provisioningType: thin
  snapshots: "true"
  storagePools: my-backend
provisioner: csi.trident.netapp.io
reclaimPolicy: Delete
volumeBindingMode: Immediate

(my-backend storage driver is “ontap-nas”)

Environment Provide accurate information about the environment to help us reproduce the issue.

• Trident version: 21.07.1
• Kubernetes version: v1.21.1+9807387
• Kubernetes orchestrator: Openshift 4.8.10
• NetApp backend types: ONTAP

To Reproduce

• Create volumesnapshotclass
• Create volumesnapshot

Expected behavior Snapshot should be created
