How to wrap Deffered into another Deferred with a custom exception? There is no coroutine context in that place, so I can't use .await()

Ok, seems like this is working:

val wrapper = CompletableDeferred<RESPONSE>()
val source: CompletableDeferred<RESPONSE> = ...
source.invokeOnCompletion(handler = {
    val ex = source.getCompletionExceptionOrNull()
    if (ex != null) wrapper.completeExceptionally(ex.wrap())
    else wrapper.complete(source.getCompleted())
})
