Why does DELETE give error?

Question

I have the following function in jquery which gives the delete in the record. It even deletes the record but does not go to the success, he goes to the error. Why will it be?

function deletar_cliente(id_cliente)
  {
    var mensagem_sucesso = "";
    var mensagem_erro = "";
    var url_cliente = "cadastro_clientes.php";
    $.ajax({
      url: url_base + "clientes/" + id_cliente,
      type: 'DELETE',
      dataType: 'json',
    }).success(function(data)
    {
      console.log(data);
    }).error(function(data)
    {
      console.log('erro');
    });
  }

CONTROLLER CUSTOMERS:

public function destroy($id)
{

    $clientes = Clientes::find($id);

    if(!$clientes) {
      return response()->json([
        'message'   => 'Cliente não encontrado',
      ], 404);
    }

    $clientes->delete();
}

ROUTES:

use Illuminate\Http\Request;

Route::get('/', function () {
  return response()->json(['message' => 'Rep Api', 'status' => 'Connected']);;
});

Route::resource('clientes', 'ClientesController');
Route::resource('fornecedores', 'FornecedoresController');
Route::resource('usuarios', 'UsuariosController');
Route::resource('estados', 'EstadosController');
Route::resource('municipios', 'MunicipiosController');
Route::post('autenticacao', 'AuthController@authenticate');
Route::get('get-municipios/{estados_id}', 'MunicipiosController@getMunicipios');

Answer 1

In your controller, force it to return a success message:

public function destroy($id){

$clientes = Clientes::find($id);

   if(!$clientes) {
     return response()->json([
       'message'   => 'Cliente não encontrado',
     ], 404);
   }

   $clientes->delete();
}

I saw in the tutorial the author forcing a 204:

return response()->json($clientes->delete(), 204);

Another try you can use:

$.ajax({
    type: 'POST',
    dataType: "json",
    cache: false,
    url: url_base + "clientes/" + id_cliente,
    success: function (response) {
        console.log(response);
    },
    error: function (response) {
        alert('Error - ' + response.responseText);
        console.log(response);
    }
});

As much as it does not solve put in the comments the errors that will return in the console or Alert.
