The expression $this->countries of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using empty($expr) instead to make it clear that you intend to check for an array without elements.

It seems like $action can also be of type null; however, parameter $action of Illuminate\Routing\Route::setAction() does only seem to accept array, maybe add an additional type check?
