I have a suspend function in which a resource is opened and later closed in a finally block. Upon cancellation I would expect to receive a CancellationException. But I don't receive any und the finally block is not executed. Does anyone know why?

03/11/2019, 4:15 PMWhere are you catching the exception? Subsequent suspend functions don’t run upon cancellation. Your best bet may be to add a cancellation exception handler on launch

Copy code
suspend fun doStuff() {
try {
val resource = openResource()
callOtherSupendFunction(resource)
} catch (e : CancellationException) {
// never reached here
} finally {
resource.close() // not executed when cancelled
}
}I found the issue. Inside
