quarkus: MutinyEmitter fails with an outbound connector configured

Describe the bug MutinyEmitter fails with java.lang.IllegalStateException: SRMSG00027: No subscriber found for the channel price-create when the channel (“price-create”) is connected to an outbound connector instead of an in-memory method annotated with @Incoming. Changing MutinyEmitter to Emitter produces the expected behavior of queuing the message.

Expected behavior Message should be sent via configured outbound connector by the application.properties

Actual behavior java.lang.IllegalStateException is thrown and no message is sent

To Reproduce Clone repo https://github.com/tcerdaITBA/quarkus-mutiny-emitter-bug

Steps to reproduce the behavior:

1. ./mvnw compile quarkus:dev
2. curl localhost:8080/hello-resteasy

Configuration

amqp-username=quarkus
amqp-password=quarkus

mp.messaging.outgoing.price-create.connector=smallrye-amqp
mp.messaging.outgoing.price-create.address=prices

mp.messaging.incoming.prices.connector=smallrye-amqp
mp.messaging.incoming.prices.durable=true
