Component used: Navigation
Version used: 2.8.0-beta02
Devices/Android versions reproduced on: Any

After migrating to use the new APIs, the last step for me was to go ahead and implement all the right typeMap: Map<KType, @JvmSuppressWildcards NavType<*>> to pass into my destinations. The stacktrace for those looked something like this:

java.lang.IllegalArgumentException: Cannot cast sections of type kotlin.collections.ArrayList to a NavType. Make sure to provide custom NavType for this argument.

But the problem is that until the last point where it does lead me to the right place (at com.hedvig.android.app.navigation.HedvigNavHostKt.HedvigNavHost$lambda$56$lambda$55(HedvigNavHost.kt:99)) from that point and up, all the references to my own code are to lines that do not match my real project. For example HomeGraph.kt:82 points to line "82" but the entire file is 71 lines.

I am not sure where this mismatch is happening, but it's making fixing the type maps a very slow job as I need to now go and manually check every single destination and manually deduce if it needs a type-map or not.
