$injector is of type object<EventEspresso\core\services\container\InjectorInterface>, but the property $injector was declared to be of type object<EventEspresso\core\services\container\DependencyInjector>. Are you sure that you always receive this specific sub-class here, or does it make sense to add an instanceof check?
