Currently, the operator tries to get the advertised listener hostnames / ports for the controller nodes in KRaft mode and use them as an annotation. This is wrong as the controller nodes do not really have any advertised listeenrs. By coincidence, the type: internal listeners were geenrating the names so everything seemed to work. But when you try to deploy a Kafka cluster without such listener, it starts throwing NPEs.
