Running Rasa with events streamed to a Kafka topic

Hi – I was trying the formbot example and was wanting to log to Kafka, but wityh no security setup for kafka. I have an endpoint.yml file with this

event_broker: url: localhost topic: rasaEvents type: kafka

but when I run rasa shell -vv -m models --endpoints endpoints.yml, I get the prompt for input, but then Rasa just hangs, and no event is published to the Kafka topic.

Is it the endpoints.yml file above that is the issue?

Thanks

Ian
