App crashes on building back stack

Question

I am building in my IntentService a back stack. I am receiving crash reports from Kitkat devices.

My code is very simple and I don't know what could be the reason. I have a stacktrace but it's not getting me anywhere. Anyone experienced something like this?

    override fun onHandleIntent(intent: Intent?) {
        if (intent != null) {
            val articleIntent = intentFor<ArticleActivity>()
            articleIntent.putExtras(intent)
            TaskStackBuilder.create(this).addNextIntent(intentFor<DrawerActivity>()).addNextIntent(articleIntent).startActivities()
        }
    }

Exception from Crashlytics
