expected exactly 1 DNS record with ID %s, got %d

Error message

expected exactly 1 DNS record with ID %s, got %d

What it means

Find filters records by ID but the zone query returned more than one record while a specific record ID was requested. Since Scaleway record IDs are unique, more than one match means inconsistent state, so Find refuses to guess and returns an error.

Solutions

1. Inspect the zone and delete the duplicate record in the Scaleway console (scw domain record list zone-name=<zone>)
2. Keep only one record per name/type pair, then re-run kops update cluster
3. If intentional round-robin is needed, remove the ID from the kOps task so it does not expect a single match

Example fix

// before (console)
api.example.com. 300 IN A 1.2.3.4
api.example.com. 300 IN A 5.6.7.8   // duplicate — delete this
// after (console)
api.example.com. 300 IN A 1.2.3.4

records, _ := cloud.DomainService().ListDNSZoneRecords(&domain.ListDNSZoneRecordsRequest{DNSZone: zone, Name: name, Type: rtype}, scw.WithContext(ctx))
if records.TotalCount > 1 && d.ID != nil {
	return fmt.Errorf("cleanup required: %d duplicate %s records for %s in %s", records.TotalCount, rtype, name, zone)
}

if records.TotalCount > 1 && d.ID != nil {
	return fmt.Errorf("expected exactly 1 DNS record with ID %s, got %d — deduplicate records in the zone first", *d.ID, records.TotalCount)
}

When it happens

Trigger: ListDNSZoneRecords returned TotalCount > 1 while d.ID != nil — i.e. the zone contains multiple records matching the requested name/type, and the request asked to narrow to a single known ID.

Common situations: Duplicate DNS records created by earlier failed kOps runs or manual console edits (same name/type added twice), or records left behind after a zone import.
