Do you have a more specific snippet? It looks like you are trying to reply twice
Also you have to respond before the suspend function returns
that means that if you are using RX you will probably have to use something like a CompletableFuture to suspend your function until the result is returned
if you don’t wait, probably the fallback handlers will be executed, and once completed, the call would have been replied by the fallback handler
