n8n - 💡(How to fix) Fix RabbitMQ trigger & Delete from queue options, not working as expected. [1 comments, 2 participants]

Bug Description

RabbitMQ trigger node behaves differently than stated.

When setting the 'delete from queue when' to 'Specifiek later in workflow': In production: message wil delete from the queue when workflow crashes. But it should be added back to the queue on crash ( would be nice ), else it should stay NACK, untill it reaches timeout, and then sent back to the queue.

In Editor mode: its hard to test, but it will stay NACK when crashed, and will stay NACK untill timeout reaches, and sends back to queue.

To Reproduce

In produciton(published).

1. make a rabbitmq trigger, and set it to a queue.
2. set it to the option, delete when delete message node is activated
3. set timer of 20 seconds, then make it crash on purpose, without reaching the delete from queue node.
4. Msg should be deleted from the queue, instead of moving back to the queue.

Expected behavior

I expect the message to be sent back to the queue on crashed workflow, and will retry on next trigger, untill it reaches the delete form queue node, then it should be deleted.

These images were a production flow, where the flow purposely failed before reaching the node delete from queue, yet it shows the msg was still deleted from the queue.
