我正在使用Laravel 10，并实现了以下控制器：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\MarketplaceItem;
use Stripe\Stripe;
use Stripe\Checkout\Session;
use Illuminate\Support\Facades\Log;

class PaymentController extends Controller
{
    /**
     * Create a new Stripe Checkout Session for the specified item.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $itemId  The ID of the item being purchased.
     * @return \Illuminate\Http\JsonResponse
     */
    public function createCheckoutSession(Request $request, $itemId)
    {
        try {
            // Fetch the specified item from the database.
            $item = MarketplaceItem::findOrFail($itemId);
            
            // Fetch the seller's Stripe account ID.
            $sellerStripeAccountId = $item->user->stripe_account_id;
            
            // Calculate the total amount for the item in cents.
            $amount = (int)($item->price * 100);
            
            // Calculate the application's commission (20% of the total amount).
            $applicationFee = (int)($amount * 0.20);

            // Set the secret API key for Stripe.
            Stripe::setApiKey(config('stripe.secret'));

            // Set the Stripe-Account header
            $options = ['stripe_account' => $sellerStripeAccountId];

            // Create a new Stripe Checkout Session.
            $session = Session::create([
                'payment_method_types' => ['card'],  // Allow card payments only.
                'line_items' => [[
                    'price_data' => [
                        'currency' => 'usd',  // Set the currency.
                        'product_data' => [
                            'name' => $item->prompt_name,  // Set the item name.
                        ],
                        'unit_amount' => $amount,  // Set the unit amount.
                    ],
                    'quantity' => 1,  // Set the quantity.
                ]],
                'mode' => 'payment',  // Set the payment mode.
                'success_url' => route('payment.success'),  // Set the success URL.
                'cancel_url' => route('payment.cancel'),  // Set the cancel URL.
                'payment_intent_data' => [
                    'application_fee_amount' => $applicationFee,  // Set the application fee amount.
                    'transfer_data' => [
                        'destination' => $sellerStripeAccountId,  // Set the destination Stripe account.
                    ],
                ],
            ], $options);  // Pass the options array here

            // Return the session ID as a JSON response.
            return response()->json(['session_id' => $session->id]);
        } catch (\Exception $e) {
            // Log the exception
            Log::error('PaymentController@createCheckoutSession: ' . $e->getMessage());

            // Optionally, you could return a generic error message to the frontend
            return response()->json(['error' => 'An error occurred while processing your payment.'], 500);
        }
    }

    /**
     * Display the payment success page.
     *
     * @return \Illuminate\View\View
     */
    public function success()
    {
        return view('payment.success');
    }

    /**
     * Display the payment cancellation page.
     *
     * @return \Illuminate\View\View
     */
    public function cancel()
    {
        return view('payment.cancel');
    }
}

我的用户有一个$sellerStripeAccountId，但我得到错误：

"The 'payment_intent_data[transfer_data][destination]' param cannot be set to your own account."

我不理解这个错误，因为当用户注册时，我给予用户一个stripe_account_id，在我的RegisterController中如下所示：

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use App\Models\User;
use App\Models\Country;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Stripe\Stripe;
use Stripe\Account;

class RegisterController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Register Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users as well as their
    | validation and creation. By default this controller uses a trait to

    */

    use RegistersUsers;

    /**
     * Where to redirect users after registration.
     *
     * @var string
     */
    protected $redirectTo = RouteServiceProvider::HOME;

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest');
    }

    public function showRegistrationForm()
    {
        $countries = Country::orderBy('name')->get();
        return view('auth.register', compact('countries'));
    }

    /**

    protected function validator(array $data)
    {
        return Validator::make($data, [

        ]);
    }

    protected function create(array $data)
    {
        $user = User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
            'country_of_origin' => $data['country_of_origin'],
        ]);

        $this->createStripeAccount($user);

        return $user;
    }

    /**
     * Create a new Stripe Account for the specified user.
     *
     * @param  \App\Models\User  $user
     * @return void
     */
    protected function createStripeAccount(User $user)
    {
        // Set your secret key. Remember to switch to your live secret key in production!
        // See your keys here: https://dashboard.stripe.com/account/apikeys
        Stripe::setApiKey(config('stripe.secret'));

        $account = Account::create([
            'type'         => 'express',
            'email'        => $user->email,
            'country'      => $user->country_of_origin,
            'capabilities' => [
                'card_payments' => ['requested' => true],
                'transfers'     => ['requested' => true],
            ],
            'settings'     => [
                'payouts' => [
                    'schedule' => [
                        'interval' => 'manual',
                    ],
                ],
            ],
        ]);

        $user->stripe_account_id = $account->id;
        $user->save();
    }
}

有什么建议我做错了吗？
感谢您的回复！
