failed to extract L3 floating ip: %v

Error message

failed to extract L3 floating ip: %v

What it means

listL3FloatingIPs wraps the ExtractFloatingIPs failure after pages are fetched, i.e. the Neutron response could not be parsed into FloatingIP objects. It fires on malformed API responses and is retried with backoff.

Solutions

1. Retry; the operation already runs inside RetryWithBackoff
2. Check gophercloud/Neutron version compatibility
3. Inspect the wrapped error for response-format anomalies
