I keep hitting those exceptions in one of my scope.launch { } blocks

kotlinx.coroutines.JobCancellationException: StandaloneCoroutine was cancelled;

Is there a way to know where this cancellation is coming from? I've put logging+breakpoints everywhere I manually cancel the job, but it's coming from somewhere else..?

Are you launching another Coroutine in this scope. I believe this can happen if you try to launch a new Coroutine after the scope is cancelled.

I'm using

launch

and

withContext

in that scope, yes

It is hard to tell without a code but where are you cancelling the scope?

outside the whole thing

If one job has an error, all its parent jobs are then cancelled. When a job is cancelled, it also cancels all its children. Thus, if a single job has an error, the entire tree of jobs is cancelled. You’ll probably want to to use a supervisorScope to manage independent parallel tasks https://kotlinlang.org/docs/reference/coroutines/exception-handling.html#supervision

I have an eventbus event, and when it receives a certain type of event it cancels the job
