Bug introduced by
The method getListeners() does not exist on Illuminate\Contracts\Events\Dispatcher. Did you maybe mean listen()?

This check marks calls to methods that do not seem to exist on an object.

This is most likely the result of a method being renamed without all references to it being renamed likewise.
