Exchange binding is not created for @Outgoing channel

[elmodeer]

I have the following setup:

@Incoming(PROCESS_VIEWS_CHANNEL)
@Outgoing(PROCESS_VIEWS_DLQ_CHANNEL)
@Acknowledgment(Strategy.MANUAL) // Enable manual ack/nack
@ActivateRequestContext
public Message<byte[]> process(Message<byte[]> message) {
  
  try {
  // some processing logic and if successful 
  return null; // to ack
  } catch(Exception e) {

   var metadata = OutgoingRabbitMQMetadata.Builder().withRoutingKey("processView.lifecycle").build();
   return message.withMetadata(Metadata.of(metadata)); // to send to the dlq
  }
} 

I also tried the following setup but the same issue exists:

  @Inject
  @Channel(PROCESS_VIEWS_DLQ_CHANNEL)
  Emitter<byte[]> failedEventsEmitter;

  @Incoming(PROCESS_VIEWS_CHANNEL)
  @Acknowledgment(Strategy.MANUAL) // Enable manual ack/nack
  @RunOnVirtualThread
  @ActivateRequestContext
  public CompletionStage<Void> process(Message<byte[]> message) {
  try {
  // some processing logic and if successful 
  return message.ack(); // to ack
  } catch(Exception e) {

      // send the event to DLQ
      failedEventsEmitter.send(message.getPayload()).toCompletableFuture().join();
      return message.ack();
  }
  

my properties looks the following:

# Rabbit channel configuration
mp.messaging.incoming.processviews.max-outstanding-messages=1
mp.messaging.incoming.processviews.connector=smallrye-rabbitmq
mp.messaging.incoming.processviews.routing-keys=processView.lifecycle
mp.messaging.incoming.processviews.queue.name=process-view-lifecycle-queue
mp.messaging.incoming.processviews.queue.single-active-consumer=true
mp.messaging.incoming.processviews.exchange.name=process-view-lifecycle-exchange
mp.messaging.incoming.processviews.exchange.type=direct

# Rabbit mq dlq configuration
mp.messaging.outgoing.processviewsdlq.connector=smallrye-rabbitmq
mp.messaging.outgoing.processviewsdlq.default-routing-key=processView.lifecycle
mp.messaging.outgoing.processviewsdlq.exchange.name=process-view-lifecycle-dlx
mp.messaging.outgoing.processviewsdlq.queue.name=process-view-lifecycle-dlq
mp.messaging.outgoing.processviewsdlq.exchange.type=direct

the problem now, is that the failed messages are not routed correctly to the outgoing exchange, i.e. process-view-lifecycle-dlx. Looking at the management ui of rabbitmq using the dev services, I find that the incoming exchange is always created eagerly and properly bound to the queue. But the outgoing exchange is only created when a message is sent and failed and then it has no binding to the queue.

so what is the issue here?

I want to use this exchange as a sink for all failed messages and then later I will have job that consume those messages.

if you ask why I am not using the dlq of rabbit itself, it is because this feature is not supported currently within my org setup for rabbit. so We have to do this custom dlx/dlq stuff.
