Php Laravel 6持续未定义变量错误

尝试访问视图中的变量时，我遇到未定义的变量错误。我在这里经历了几个解决方案，但没有一个对我有效。我已经彻底检查了mu代码中可能导致此错误的所有内容，但根本找不到任何内容，请协助

控制器

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Product;
use App\Category;
use App\Depot;
use Illuminate\Support\Facades\DB;
use Gloudemans\Shoppingcart\Facades\Cart;
use Auth;

class CheckoutController extends Controller
{
    public function index()
    {
        $allcategories=Category::get();
        $delivery_method = DB::table('deliverymethods')
            ->get();
        $cartItems=Cart::content();
        return view('checkout.index',['delivery_method'=>$delivery_method],['allcategories'=>$allcategories]);
    }

    public function deliverymethod()
    {
        $cartItems=Cart::content();
        $allcategories=Category::get();
        return view('delivery.index',['cartItems'=>$cartItems],['allcategories'=>$allcategories]);
    }

    public function billinginfo()
    {
        $depots=Depot::get();
        $cartItems=Cart::content();
        $allcategories=Category::get();
        return view('billing.index',compact('cartItems'),['allcategories'=>$allcategories],['depots'=>$depots]);
    }

    public function shipping(Request $request)
    {
        $user_id=Auth::user()->id;
        $shippingaddress=DB::table('shippingaddresses')
                        ->select('shippingaddresses.*')
                        ->where('user_id',$user_id)
                        ->get();

        $cartItems=Cart::content();
        $allcategories=Category::get();
        return view('shipping.index',['cartItems'=>$cartItems],['allcategories'=>$allcategories],['shippingaddress'=>$shippingaddress]);
    }
}

尝试将多个集合分组到一个数组中，然后将其发送到

$viewData = [
    'cartItems'  => $cartItems,
    'allcategories'   => $allcategories,
    'shippingaddress' => $shippingaddress
];

return View::make('shipping.index')->with($viewData);
