Is there a solution to propagate request scoped cdi bean to a consumer with calling EventBus request? - events

Question

I'm trying to use quarkus-rest-client-reactive to call a rest api, and the rest-client calling is in a #ConsumeEvent method.
But, now it doesn't work because the authorization header on the request message is not set, and I noticed that when I call the consume event with using a EventBus request, a request scoped cdi bean is not properly propagated.
I'm refering the example https://ja.quarkus.io/guides/reactive-event-bus.
It is said then 'You can inject an executor if you use the Context Propagation extension'.
Please tell me how to propagate request scoped bean when I'm using EventBus request.

It worked when I use event.fireAsync and #ObservesAsync, but I couldn't get a return value so I can't use this means.

_service.name(file.getId())
.onItem().invoke(name -> file.setName(name))
.onItem().transform(name -> file)
.subscribeAsCompletionStage();
}
}
And I tried to add an emitOn() with a ManagedExecutor before EventBus.request calling, but it doesn't work.
