missing volume IDs

Error message

missing volume IDs

What it means

Guard in the CSIVolume.Deregister RPC: the request's VolumeIDs list is empty, so there are no volumes to deregister; supply at least one volume ID.

Solutions

1. Populate args.VolumeIDs with the IDs to deregister
2. Verify the upstream step that produces the ID list returned results
3. Add a client-side length check before calling deregister

Example fix

// before
args := structs.CSIVolumeDeregisterRequest{VolumeIDs: []string{}}
// after
args := structs.CSIVolumeDeregisterRequest{VolumeIDs: []string{"my-volume"}}

if len(args.VolumeIDs) == 0 {
    return errors.New("volumeIDs must not be empty")
}

if err != nil && strings.Contains(err.Error(), "missing volume IDs") { fix ID list and retry }

When it happens

Trigger: Calling CSIVolumeDeregister with args.VolumeIDs empty, e.g. scripted API calls where the ID list failed to populate.

Common situations: Empty variable expansion in scripts; automation passing an empty array after an upstream listing returned nothing.
