Hi all, how to catch exception thrown by callbackFlow ?

fun connect():Flow<Item> = callbackFlow {
    check(1 == 0) // This is expected to throw an IllegalStateException
}

Hi, just like for another flow, around the terminal operator (i.e. collect { … } or what's calling it under the hood, like first() or something else.

You can also use the catch { … } operator if it suits your use case.

i have

connect()
.catch{}
.first()

but still can’t catch the exception

.first() will fail if the flow is empty, as in your example. this is unrelated to the exception within your flow
