<?php

use IlluminateSupportFacadesRoute;
use AppHttpControllershomeController;
use AppHttpControllersvideoController;
use AppHttpControllersloginController;
use AppHttpControllerspayController;

Route::get('/', [homeController::class, 'index'])->name('home');

Route::get('/login', [loginController::class, 'index'])->name('login');

Route::get('/{id}', [videoController::class, 'play'])->name('play');

Route::post('/verify', [loginController::class, 'verify'])->name('verify');

Route::post('/ver', [loginController::class, 'doverify'])->name('doverify');

Route::get('/pay', [payController::class, 'index'])->name('pay');

this is my vodplay component`s class, where i get error from:

<?php

namespace AppViewComponents;

use Closure;
use IlluminateContractsViewView;
use IlluminateViewComponent;
use AppModelsVideo;
use AppModelsorderModel;
use AppModelsUser;
use ShetabitMultipayInvoice;
use ShetabitPaymentFacadePayment;

class vodplay extends Component
{
    /**
     * Create a new component instance.
     */
    public $iding;
    public function __construct($iding)
    {
        //
        $this->id = $iding;
    }

    /**
     * Get the view / contents that represent the component.
     */
    public function render(): View|Closure|string
    {
        
        $price = video::where('id',$this->id)->first();
        $price = $price->price;
        // dd($price);
        $videodata = video::where('id',$this->id)->first();
        
        if ($price == '0' || $price == NULL) {
            return view('components.vodplay')->with('videodata',$videodata);
        } else {
            // Do all things together in a single line.
            return Payment::purchase(
            (new Invoice)->amount($price), 
            function($driver, $transactionId) {
            // Store transactionId in database.
            // We need the transactionId to verify payment in the future.
            }
            )->pay()->render();
        }
    }
}

and this is my sample payController file:

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;

class payController extends Controller
{
    //
    public function index() {
        echo "hello";
    }
}
