In csi-driver:latest, the availability zone detection is partially broken, due to the fact that HCloud Metadata Service does not return the availability zone for older servers, or servers that have been created from a snapshot, see this issue.
Also, the metadata query result is not validated, so the metdata service error response availability-zone not found becomes csi.hetzner.cloud/location=availability.
