Observation. As there are no restart happened with csi-snapshot-controller, getting logs for this pod with non existed container throwing message as
"Error from server (BadRequest): previous terminated container"
Execution steps
1. Created sno cluster

csi-snapshot-webhook-696b489f7b-z95sq 1/1 Running 0 77m
3. Triggered the oc path command
