Place Order Error

[kestraly]

What I expected

Place Order Without Error

What happened instead

Checkout continues to indefinitely load, email is sent to customer with order number, payment fails

Amazon\Pay\Model\CheckoutSessionManagement::setOrderPendingPaymentReview() must be an instance of Amazon\Pay\Model\mixed, string given, called in vendor/amzn/amazon-pay-magento-2-module/Controller/Checkout/PlaceOrder.php on line 93

Steps to reproduce the issue

Try and checkout with guest checkout, automatic capture.

Your setup

• Magento version: 2.4.5-p8
• Swissup FireCheckout (Maybe cause)
• Amazon Pay Extension Version: 5.17.1
• Magento Edition: Community
• JavaScript Console: 500 error
