Symptoms
When creating a Pod with Longhorn Volume as PVC, the Pod cannot start.
When checking for error message using kubectl describe <pod>, the following message is shown:
Warning FailedAttachVolume 4m29s (x3 over 5m33s) attachdetach-controller AttachVolume.Attach failed for volume "pvc-xxx" : rpc error: code = Internal desc = Bad response statusCode [500].

Body: [message=unable to attach volume pvc-xxx to node-xxx: volume pvc-xxx not scheduled, code=Server Error, detail=] from [http://longhorn-backend:9500/v1/volumes/pvc-xxx?action=attach]
Noticed the message returned by Longhorn in the error above:
