Having multiple Kafka Triggers doesn't trigger

Describe the problem/error/question

I want to consume messages off multiple Kafka Topics. I’ve used the Kafka Trigger before, to consume messages of a single Topic (successfully). When I add a second Kafka Trigger to my workflow, neither trigger is triggered anymore.

To reproduce. I’ve setup two topics “test1” and “test2” - and I’m using kafka-console-producer to fire the message.

What is the error message (if any)?

No error in logs afaik.

Please share your workflow

Can provide if required

Share the output returned by the last node

Silly mistake - make sure the “Group Id” value is unique!

Would make a good addition to the docs: Kafka Trigger node documentation | n8n Docs
