In the kotlin playground (play.kotlinlang.org), is there a way to print out an uncaught exception from a Coroutine (when calling

launch

from a scope without a CoroutineExceptionHandler)? Update: Solved

It prints the stacktrace for me, eg

fun main() {
    error("test")
}

prints

Exception in thread "main" java.lang.IllegalStateException: test
   at FileKt.main (File.kt:2) 
   at FileKt.main (File.kt:-1)

Do you want something different?

I see nothing….

This code-snippet finishes the Coroutine with an exception and without a CoroutineExceptionHandler, the Thread’s default uncaught-exception-handler should handle it. But I can set the default-exception handler (security issue: not allowed on the playground)

Ah coroutines, I don't know about that, sorry.

Solved: I ‘accidentally’ threw a CancellationException. Thank you!
