unable to parse Scaleway zone %q: %w

Error message

unable to parse Scaleway zone %q: %w

What it means

In VerifyToken, scw.Zone could not be constructed from the zone string found in the server's metadata — the metadata returned a malformed or SDK-unknown zone identifier, so the zone needed to target API calls for this node is unusable.

Solutions

1. Check the wrapped error and the metadata-reported zone value
2. Verify the node's zone matches zones known to the vendored Scaleway SDK
3. Update kOps so the SDK version knows the node's zone
