[ECP-9534] Success page displayed if payment is canceled

[dimitriBouteille]

Hello !

There is a small bug with the payment method Twint with classic magento - I have not tested with the other methods - in headless integration (graphql) no problem :

• On the test environment, if the client goes to /adyen/return twice, the page /checkout/success is displayed the second time.
• On the production env, if the customer clicks Cancel payment, the success page is displayed.

The problem between the two environments is slightly different but the source is the same: the function Adyen\Payment\Controller\Return\Index::validateRedirectResponse().

validateRedirectResponse :

When calling the /adyen/return for the first time, this function returns false.

On the second call, there is a check using the isResponseAlreadyProcessed function to verify whether the payment has already been processed or not. The problem is that isResponseAlreadyProcessed returns true.

The isResponseAlreadyProcessed function is based on the order history to know if the reference PSP reference exists in the comments. On the second call, there is a comment with the PSP reference and returns true without checking if the payment is valid, canceled, ...

https://github.com/Adyen/adyen-magento2/blob/e3af5ed622fce24d449cf0be3373071c3d59a8c3/Controller/Return/Index.php#L198-L216

Here is what happens globally :

• First call to /adyen/return
• Save order history with PSP reference
• validateRedirectResponse return false
• Redirect to /cart with error
• Second call to /adyen/return
• isResponseAlreadyProcessed returns true because the PSP reference exist in order comment history
• validateRedirectResponse returns true
• Redirect to /checkout/success with canceled error -_-

To Reproduce

In testing environment :

• Place order with Twint method
• Cancel payment
• /checkout/cart page is displayed with error (payment canceled)
• Call /adyen/return with same arguments
• /checkout/success is displayed with error (payment canceled)

In production environment :

• Place order with Twint method
• Click on Cancel payment in Twint interface
• /checkout/success is displayed with error (payment canceled)

Between the production and test env, there is a difference since on the production environment Twint or Adyen makes two calls to /adyen/return, I do not know why:( Here is an example of the logs in production :

Expected behavior

If customer cancel payment, page /checkout/cart must be displayed in all cases with error (e.g: Payment canceled).
