Payment Method not in Payload when "Payment" is not the last step of the Checkout

[bscthartmann]

Describe the bug
We adjusted the Hyva Checkout to have 3 Steps

• Shipping
• Payment
• Review

When the Review Step in active the Checkout response with a Payment Method Problem and the Adyen error log says that the Method is missing (AdyenLoggerTest.ERROR: Required object 'paymentMethod' is not provided.). As soon as I deactivate the review step, it works fine.

The Review Step is just about showing an overview and about accepting TOC.

To Reproduce
Steps to reproduce the behavior:
Make a 3 Step Hyva Checkout with a overview step in the end and go through checkout.

Expected behavior
Payment works fine

Magento version
2.4.7

Plugin version
adyen/module-hyva-checkout 1.2.3
adyen/module-payment 9.13.0

Update:

I compared the method \Adyen\Hyva\Magewire\Payment\Method\AdyenPaymentComponent::placeOrder with and without the review step and I could identify that the $datathat is given to the method differs.

This lead me to check where the $data parameter comes from and I found out that the placeOrder method is executed by JavaScript (vendor/adyen/module-hyva-checkout/view/frontend/templates/payment/model/adyen-payment-method.phtml) where the $data is collected. This all happens in the JavaScript File and Method placeOrder(data, publicHash = null).

Since we have the review step added, this JavaScript method is never executed and therefore the call to placeOrder happens the HyvaCheckout native way, without the needed data.
