failed to extract dns zone pages: %s

Error message

failed to extract dns zone pages: %s

What it means

listDNSZones wraps the gophercloud zones.ExtractZones error after a successful AllPages call, i.e. the Designate API returned pages that could not be parsed into zone objects. It fires on malformed/unexpected Designate responses and is retried with backoff by the caller.

Solutions

1. Retry; the operation already runs inside RetryWithBackoff
2. Check OpenStack Designate service version compatibility with gophercloud
3. Inspect the wrapped error for API response anomalies
