GCP Funqy CloudEventsFunction and Kotlin Coroutines

[mdietrichstein]

Hi,

I'm attempting to deploy a reactive/async CloudEventsFunction to Google Cloud, and we are using Kotlin. I would like to implement the function reactively, which, according to the docs, is supported. All I need to do is return a Uni.

So, my function currently looks like this:

class FirestoreChangeHandler {
    @Funq
    fun accept(event: CloudEvent): Uni<Void?> {
        // do some work
    }
}

This works. However, I now want to use Kotlin coroutines with mutiny-kotlin like this:

class FirestoreChangeHandler {
    @Funq
    fun accept(event: CloudEvent): Uni<Void?> {
        GlobalScope.async {
            // do some work
            null
        }.asUni()
    }
}

The issue is that CDI breaks. Specifically, in my case, accessing any @RequestScoped dependency results in an error stating that RequestScope is not active. I'm fairly certain that the reason for this is the closure in GlobalScope.async running on a different thread. Is there a way to integrate Quarkus, Mutiny, and Kotlin so that this works?

Thanks!
