deleting cloud instance %s of group %s: %w

Error message

deleting cloud instance %s of group %s: %w

What it means

DeleteInstance first calls instanceAPI.GetServer then DeleteServer via the Scaleway instance API. A 404 is treated as success (already deleted); any other error from the GetServer call is wrapped as "deleting cloud instance %s of group %s: %w". This error means the instance could not even be looked up before deletion.

Solutions

1. Check the wrapped Scaleway error type (scw response error status) for 403/404/unknown-zone details.
2. Confirm the configured zone (cluster tags 'zone' or SCW profile default zone) matches where the server actually lives.
3. Ensure the credentials/IAM policy allow reading servers (servers:read) in the project.
4. If the server was already deleted elsewhere, nothing is needed — verify the ID is correct and retry.

Example fix

// before: zone mismatch
zone = scw.Zone("nl-ams-1") // server is in fr-par-1
// after
zone = scw.Zone("fr-par-1")

err := cloud.DeleteInstance(inst)
if err != nil {
  var respErr *scw.ResponseError
  if errors.As(err, &respErr) {
    switch respErr.StatusCode {
    case 403:
      klog.Errorf("permission denied deleting %s — check IAM servers:delete", inst.ID)
    case 404:
      klog.Infof("instance %s already deleted", inst.ID)
    default:
      klog.Errorf("delete failed for %s: %v", inst.ID, err)
    }
  }
  return err
}

When it happens

Trigger: instanceAPI.GetServer(&instance.GetServerRequest{Zone: s.zone, ServerID: i.ID}) fails with a non-404 error: invalid/expired credentials, wrong zone configured, server ID not a UUID, permission denied, or transient API/network failure.

Common situations: Cluster tags specify a zone different from the zone in the Scaleway profile; stale instance-group state referencing a server removed out-of-band in another zone; IAM key without servers:read scope; Scaleway API outage.
