Hi all, i have created extension function await to get document from firestore database. But when i'm using it like below, exception is thrown and my crashes

Exception_is_not_caught_even_if_i_have__try_cath__block.kt

Had something similar, and if I remember correctly solved it by catching Throwable instead of Exception

[Kulwinder Singh]

i have tried to replace it with Throwable but still app is crashing

Do you have a stacktrace

I don't think this exception is related to the code you've shown us. Wouldn't you agree?

[Kulwinder Singh]

but my Question is that catch block is not catching this exception

[Dico]

Then maybe it's result.result throwing it when it's not successful.

[Dico]

You should try reversing the two conditions

[Kulwinder Singh]

suspend fun <T> Task<T>.await(): T = suspendCancellableCoroutine { continuation ->
    this.addOnSuccessListener(continuation::resume)
            .addOnFailureListener { continuation.resumeWithException(it) }
            .addOnCanceledListener { continuation.cancel() }
}

Changing await to this worked

Hey @Kulwinder Singh, could you provide a reproducer in that issue I raised, in reply to last comment? https://github.com/Kotlin/kotlinx.coroutines/issues/1197#issuecomment-494425635
