i have set of controller all of them are working , except controller called RestaurantsController , however the old routes in it are working when i add to it new route are not recognized and i got error :

(2/2) NotFoundHttpException No query results for model [App\Restaurant] hello

in Handler.php line 131 at Handler->prepareException(object(ModelNotFoundException)) in Handler.php line 109 at Handler->render(object(Request), object(ModelNotFoundException)) in Handler.php line 47 at Handler->render(object(Request), object(ModelNotFoundException))

however the routes and controller is defined correctly :

Route::prefix('restaurants')->group(function (){

Route::get('/', 'RestaurantsController@index')->name('Restaurants.list');
Route::post('/', 'RestaurantsController@store');
Route::get('/create', 'RestaurantsController@create');
Route::get('/{restaurant}', 'RestaurantsController@showprofile')->name('restaurant.showprofile');
Route::put('/{restaurant}', 'RestaurantsController@update');
Route::delete('/{restaurant}', 'RestaurantsController@destroy');
Route::get('/{restaurant}/edit', 'RestaurantsController@edit');
Route::get('/hello', 'RestaurantsController@hello');

// Route::post('/registerrestaurant_store', 'RestaurantsController@register_restaurant_store');

});
