İyzico redirec-page sayfası halen boş geliyor.

Hi,
I am using bagisto 1.4.5 and your extension
after checkout and payment in iyzico sandbox, i get this error in the image below

It needs to redirect callback url by pressing the payment button. But even though the GET method is used, the POST method error comes up.

Issue Description

We are encountering an error similar to this when the request returns successfully:
Call to undefined method Webkul\Checkout\Cart::prepareDataForOrder()
This error is preventing the progression to complete the payment process and create the order.

Preconditions

OS: Windows 10 pro
Browser: Chrome 123.0.6312.122 Release
PHP 8.1

Expected Result

• redirect() Method: This method redirects the user to the Iyzico server to initiate the payment process. It collects necessary information from the shopping cart (such as billing address, shipping address, items, and total amount) and creates a checkout form request to be sent to Iyzico. Once the request is processed successfully, it renders a view with the payment form for the user to proceed with the payment.

• callback() Method: After the payment process is completed on the Iyzico server, the user is redirected back to the application with a token. This method retrieves the checkout form details using the token and checks the payment status. If the payment is successful, it redirects the user to the success route; otherwise, it redirects to the cart page with an error message.

• success() Method: When the payment is successful and the user is redirected to the success route, this method creates an order using the data from the shopping cart. It deactivates the cart, flashes the order details into the session, and redirects the user to the checkout success page.

• failure() Method: If the payment process fails or is cancelled, this method flashes an error message indicating the failure reason and redirects the user back to the cart page.

• prepareInvoiceData() Method: This method prepares the data necessary for creating an invoice for the order. It iterates over each item in the order and prepares the invoice data accordingly.
