ReflectionException in Container.php line 681:

Hello guys I'm a beginner in lumen and was trying to set up controllers, but I'm having a trouble (Class App\Http\Controllers\App\Http\Controllers\ArticuloController does not exist). Can you help me?

My controller

class ArticuloController extends Controller{
 
 
    public function index(){
 
        $articulo  = Articulo::all();
 
        return response()->json($articulo);
 
    }
 
    public function getArticulo($id){
 
        $articulo  = Articulo::find($id);
 
        return response()->json($articulo);
    }
 
    public function saveArticulo(Request $request){
 
        $articulo = Articulo::create($request->all());
 
        return response()->json($articulo);
 
    }
 
    public function deleteArticulo($id){
        $articulo  = Articulo::find($id);
 
        $articulo->delete();
 
        return response()->json('success');
    }
 
    public function updateArticulo(Request $request,$id){
        $articulo  = Articulo::find($id);
 
        $articulo->title = $request->input('title');
        $articulo->content = $request->input('content');
 
        $article->save();
 
        return response()->json($article);
    }
 
}

Route file

$app->get('/', function () {
    return view('dist.index');
});

$app->get('api/articulo','App\Http\Controllers\ArticuloController@index');
 
$app->get('api/articulo/{id}','App\Http\Controllers\ArticuloController@getArticulo');
 
$app->post('api/articulo','App\Http\Controllers\ArticuloController@saveArticulo');
 
$app->put('api/articulo/{id}','App\Http\Controllers\ArticuloController@updateArticulo');
 
$app->delete('api/articulo/{id}','App\Http\Controllers\ArticuloController@deleteArticulo');
