Laravel 5.4 с Yajra\DataTables 7 Кнопка Excel и страница печати печати не найдена

Question

У меня проблема при нажатии кнопки экспорта в Excel и печати кнопки с использованием таблиц данных в качестве службы, всегда показывая страницу не найдена и URL-адрес в браузере http://localhost:4131/master/&draw=1&columns%5B0%5D%5Bdata%5D=r ..

Вот мой код:

App \ Datatables:

public function html()
{
    return $this->builder()
                ->columns($this->setColumns())
                ->parameters($this->setParameters())
                ->ajax([
                    'type' => 'POST',
                    'data' => '{"_method":"GET","productIsActive":$("#productIsActive").val(),_token:window.Laravel.csrfToken}'
                ]);
}

protected function setParameters()
{
    return [
        'dom'          => 'Bfrtip',
        'buttons'      => ['export', 'print', 'reset', 'reload'],
        "rowCallback"  => "function( row, data ) {
            if ( $.inArray(data.DT_RowId, selected) !== -1 ) {
                $(row).addClass('selected');
                if (productIsActive) $(row).addClass('warning');
                else $(row).addClass('success');
            }

            if (! $(row).hasClass('row_clicked')) {
                $(row).addClass('row_clicked');
            }
        }"
    ];
}

App \ Html \ Controller:

namespace App\Http\Controllers\Masters;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

use App\Product;
use App\Category;
use App\Supplier;

use App\Http\Requests\ProductRequest;
use App\DataTables\Masters\ProductsDataTable;

class ProductsController extends Controller
{
    private $data;

    public function __construct() 
    {
        $this->middleware('auth');
        $this->data['productIsActive'] = true;
    }

    public function index(ProductsDataTable $dataTable)
    {       
        $this->data['page_title'] = 'List All Products';    
        return $dataTable->render('masters.products.index', $this->data);
    }

Ресурсы \ Просмотр:

@extends('masters.products.content')

@section('productBox')
{!! Form::hidden('productIsActive', $productIsActive, ['id' => 'productIsActive']) !!}
{!! $dataTable->table(['id'=>'products_table', 'class' => 'table table-bordered table-condensed'], true) !!}
@endsection

@push('partjs')
    <link rel="stylesheet" href="{{ asset('vendor/datatables/datatables.min.css') }}"> <!-- datatables builder css 1.10.13-->
    <script src="{{ asset('vendor/datatables/datatables.min.js') }}"></script> <!-- datatables builder js 1.10.13-->
    <script src="{{ asset('vendor/datatables/buttons.server-side.js') }}"></script>
{!! $dataTable->scripts() !!}
@endpush

Route \ web:

Route::group(['prefix' => '/master', 'as' =>'master.','middleware' => ['auth']], function () {
    Route::resource('/products', 'Masters\ProductsController');
    Route::resource('/categories', 'Masters\CategoriesController');
    Route::resource('/suppliers', 'Masters\SuppliersController');
});

Config \ app:

'providers' => [
..
        Yajra\Datatables\DatatablesServiceProvider::class,      
        Yajra\Datatables\ButtonsServiceProvider::class,
..

Я решаю эту проблему после добавления '?' в URL от AJAX

public function html()
{
    return $this->builder()
        ->columns($this->setColumns())
        ->parameters($this->setParameters())
        ->ajax([
            'url'  => \Request::url().'?',
            'type' => 'POST',
            'data' => '{"_method":"GET","productIsActive":$("#productIsActive").val(),_token:window.Laravel.csrfToken}'
        ]);
}
