Adding PersistentVolumeClaim on a different namespace with error 'failed to provision volume with StorageClass.. Missing provisioningMode parameter"

I am following https://docs.aws.amazon.com/eks/latest/userguide/efs-csi.html to link EFS to EKS. I have two namespace under my k8s clusters: dev and stage, and from I understand, I'd need to have two PersistentVolumeClaims that map to the shared PersistentVolume and StorageClass. So after I ran below 3 commands:

kubectl apply -f specs/pv.yaml
kubectl apply -f specs/claim.yaml
kubectl apply -f specs/storageclass.yaml

and from kubectl get sc,pv,pvc1 -n dev, I am able to see all 3 items just fine. However, as I tried to add to stage namespace - kubectl apply -f specs/claim.yaml --namespace=stage, I got below errors as efs-claim becomes stuck in a forever PENDING status:

Name:          efs-claim
Namespace:     stage
StorageClass:  efs-sc
Status:        Pending

What is causing

efs.csi.aws.com_ip-xxx failed to provision volume with StorageClass "efs-sc": rpc error: code = InvalidArgument desc = Missing provisioningMode parameter

I did not have to provide such parameter on dev namespace so why it is required for a different namespace like stage?

To resolve the error that you are seeing, re-apply your StorageClass with:

...
parameters:
  provisioningMode: efs-ap
  fileSystemId: <ID of the file system created on EFS>
...

If multiple pods going to read/write to the file system, re-apply PersistentVolume with:

...
spec:
  ...
  accessModes:
  - ReadWriteMany
...

Should the problem persist do post your StorageClass, PersistentVolumeClaim and PersistentVolume spec in your question.
