Integration Server 10.7, Kafka adapter 9.6 Fix 14

Kafka listeners are not showing up in the IS admin page. It is showing the following error. We are able to view Kafka connections fine. I have even uninstalled the adapter and reinstalled. We have installed the latest available Kafka adapter fix (fix 14). The error comes from the service that is in WmART package. Running the same in Designer fails with the same error.

com.wm.pkg.art.error.DetailedServiceException: [ART.115.3220] Adapter Runtime (Listener): Unable to get list of listener types supported by node com.wm.adapter.wmkafka.KafkaAdapter.

It used to show everything fine and we don’t know what changed which is showing this error. We are not able to enable the listeners using the IS service either.

Any suggestions to troubleshoot would be great.

wm.art.admin.connection:listResources

There was a producer and topic to which it was posting did not exist any more on the Kafka server. This seems to have been throwing a null pointer exception which apparently prevented any listener to load. As absurd as it sounds, after disabling it the page loaded again.
