I'm trying to debug an exception that gets thrown ...

# coroutines

I'm trying to debug an exception that gets thrown deep inside some coroutine calls.

I'm using Spring and I'd like kotlinx.coroutines.debug to be enabled both in production and in tests, so I've added a @Configuration and I've confirmed that this runs:

DebugProbes.sanitizeStackTraces = false
DebugProbes.enableCreationStackTraces = enableCreationStackTraces // disabled for prod, enabled for tests

System.setProperty(
  kotlinx.coroutines.DEBUG_PROPERTY_NAME,
  kotlinx.coroutines.DEBUG_PROPERTY_VALUE_ON
)

DebugProbes.install()

But I still get a super limited stack trace when I run my test. Is this the right way to set it up? I've also added a @CoroutinesTimeout to my test class but that didn't help either.

What am I missing?

Maybe https://github.com/Anamorphosee/stacktrace-decoroutinator could help.

Thanks 🙂 ended up using this and it works - although it's a bit worrying that this functionality requires a third party library. Would have thought I could get it working with the official Kotlin one

The official Kotlin solution for stack trace recovery works only when the exception submitted to the coroutine explicitly (through method “resumeWith”). Decoroutinator works in any case. If you’d like to support Decoroutinator officially please vote for https://youtrack.jetbrains.com/issue/KT-50720/Kotlinx.coroutines-debugging-Support-Stacktrace-decoroutinator-like-solution.

Thanks, voted! Didn't realise you were the author at first. Congrats for the cool library, appreciate your effort 🙏
