Hey folks, I'm trying to log exception on iOS via

throwable.stackTraceToString()

. But calling this API crashes with

ncorrectDereferenceException: Trying to access top level value not marked as @ThreadLocal or @SharedImmutable from non-main thread

exception and from stack trace of crash on iOS looks like it happens inside Throwable:

Did anyone run into this as well? Also just ran quick test by doing this

val tmp = RuntimeException().getStackTrace()

it crashes as well

I've managed to get around this by freezing the

Throwable

before calling

stackTraceToString()

agh, thx for advice....going to check

Let me know if that works 🙂

no, not working for me 😞

Sorry then I don't know 😞

it's super weird that this fails:

RuntimeException().freeze().printStackTrace()
