[BUG] transfer-pvc sets ingressClassName as null

[legolego621]

What version of crane are you running, and what are your clutsters+platform crane version: v0.0.5 I use kubernetes cluster (kubeadm installed ) I have ingress-nginx controller with default ingressclass nginx

apiVersion: networking.k8s.io/v1
kind: IngressClass
metadata:
  annotations:
    ingressclass.kubernetes.io/is-default-class: "true"
    meta.helm.sh/release-name: ingress-nginx
    meta.helm.sh/release-namespace: ingress-nginx

What actually happened?

I try to migrate pvc from one cluster to other.

./crane transfer-pvc \
    --endpoint=nginx-ingress \
    --subdomain="nginx" \
    --source-context=infradoms \
    --pvc-namespace=zabbix:test \
    --pvc-name=zabbix-server-var-tmp-pvc \
    --destination-context=infradoms-test \
    --dest-storage-class=nfs-csi-fast-delete \
    --dest-storage-requests=1Gi \
    --debug \
    --verify

I have error
