In crashlytics I'm seeing bunch of caught exceptions like this

Non-fatal Exception: kotlinx.coroutines.flow.internal.ChildCancelledException: Child of the scoped flow was cancelled

Non-fatal Exception: kotlinx.coroutines.JobCancellationException: Job was cancelled

and no stacktrace; are there supposed to be ignored?

You're likely catching all

Exception

or `Throwable`s in a suspending function.

yes, to map it into a Either monad thing

You should ignore

CancellationException

subclasses.

Btw I noticed this during development in

flatMapLatest

mostly

In order for Coroutines to properly cancel,

CancellationException

must not be swallowed.

its just logged,

.onCompletion { t -> if (t != null) log(t) }

thanks for you help!
