How to setup/configure dead letter queues

[JamieCee20]

So I have my exchange and queues in place, I then have a dead-letter queue binded to a dead-letter exchange. But when my job fails, nothing is happening, nothing appears in my dead-letter queue. I cant for the life of me, find out why

I was facing the same issue. In my case, I just need to set config properly.

'exchange' => 'application-x',
'exchange_type' => 'topic', // Exchange name
'exchange_routing_key' => '', // Dead letter exchange key

However, I need to set to config in RabbitMQ, too. You need to check arguments to support dlx
