What it means

The switch over spec.api.loadBalancer.type hit the default case in the Scaleway LB builder: the configured type matches neither Public nor Internal. It indicates an unrecognized/unsupported enum value for this provider.

Solutions

1. Set spec.api.loadBalancer.type to a supported value (Public) in the cluster spec
2. Upgrade kOps if a newer load-balancer type is expected to be supported
