I am using azure csi disk driver method for implementing K8 persistent volume. I have installed azure-csi-drivers in my K8 cluster and using below mentioned files as end-to-end testing purpose but my deployment is getting failed due to following error :

Warning FailedAttachVolume 23s (x7 over 55s) attachdetach-controller AttachVolume.Attach failed for volume "pv-azuredisk-csi" : rpc error: code = NotFound desc = Volume not found, failed with error: could not get disk name from /subscriptions/464f9a13-7g6o-730g-hqi4-6ld2802re6z1/resourcegroups/560d_RTT_HOT_ENV_RG/providers/Microsoft.Compute/disks/560d-RTT-PVDisk, correct format: ./subscriptions/(?:.)/resourceGroups/(?:.*)/providers/Microsoft.Compute/disks/(.+)

Note: I have checked multiple times, my URL is correct but I am not sure if underscore in resource group name is creating any problem, RG = "560d_RTT_HOT_ENV_RG". Please suggest if anyone have any idea what is going wrong?

K8 version : 14.9
CSI drivers : v0.3.0
