providerID %q not recognized for node %s: %w

Error message

providerID %q not recognized for node %s: %w

What it means

The node's spec.providerID does not parse as a Linode provider ID: after the linode:// prefix check and path parsing, no numeric instance ID remained (parseInstanceIDFromProviderID failed). The offending value is shown in the message.

Solutions

1. Correct node.spec.providerID to linode://<numeric-instance-id>
2. Check which integration stamped the malformed provider ID
