Business Events not working in Free Apps above 10.0

0
Hi all,   I've been looking into Business events using the pathways and playing around with my own free apps.    For some reason, unless I use Mendix 10.0, I get an Kafka error:   09:17:14app[TaskQueueDispatcher-BusinessEvents.Producer_Queue-1] INFO org.apache.kafka.clients.producer.KafkaProducer - [Producer clientId=producer-1] Instantiated an idempotent producer. 09:17:14app[TaskQueueDispatcher-BusinessEvents.Producer_Queue-1] INFO org.apache.kafka.clients.producer.KafkaProducer - [Producer clientId=producer-1] Closing the Kafka producer with timeoutMillis = 0 ms. 09:17:14app[TaskQueueDispatcher-BusinessEvents.Producer_Queue-1] INFO org.apache.kafka.common.metrics.Metrics - Metrics scheduler closed 09:17:14app[TaskQueueDispatcher-BusinessEvents.Producer_Queue-1] INFO org.apache.kafka.common.metrics.Metrics - Closing reporter org.apache.kafka.common.metrics.JmxReporter 09:17:14app[TaskQueueDispatcher-BusinessEvents.Producer_Queue-1] INFO org.apache.kafka.common.metrics.Metrics - Metrics reporters closed 09:17:14app[TaskQueueDispatcher-BusinessEvents.Producer_Queue-1] INFO org.apache.kafka.common.utils.AppInfoParser - App info kafka.producer for producer-1 unregistered 09:17:14appERRORBusinessEvents: EventID e9e580e0-188d-4a78-9e5c-2c44d6469f85 failed to send due to error Failed to construct kafka producer.   I can't find anything anywhere to suggest what is causing this or how to fix it. I really don't want to go back to Mendix 10.0 for my PoC's when demoing stuff to people.   Has anyone else had this issue or found a fix?   Thanks.

On the off chance someone else has this problem and ends up in this thread.

 

Adding a consuming business event fixes the issue. The error only occurs when there is only a publishing event in the application.

 

Discussed this with Mendix support and they are aware of the issue.
