Describe the bug

Warning: Trying to access array offset on null in /var/www/html/vendor/adyen/module-payment/Helper/Creditmemo.php on line 110

Looks like the payment is never stored in database as it should.

Happens since we upgraded :

• from Magento 2.4.7-p3 to 2.4.7-p4
• from PHP 8.2 to PHP 8.3
• from Adyen 9.14.0 to 9.14.1

EDIT : Seems that we just have an issue with our webhook configuration. But still, it should not fail on a warning.

To Reproduce
Steps to reproduce the behavior:

1. Place order
2. Invoice & Refund

Magento version

2.4.7-p4 / PHP 8.3

Plugin version

9.14.1

Hello @Nuranto,

Thank you for creating this issue!

I have a feeling that the record for this payment authorisation is missing in adyen_order_payment table. It might be due to an issue occurred during AUTHORISATION webhook handling as you mentioned in your edit.

Could you please confirm that this issue occurs due to missing record in the table adyen_order_payment and what is the order state after processing AUTHORISATION webhook?

We can add a try-catch to prevent this happening but ideally there must be a record in adyen_order_payment for the given payment attempt. Even though, we can skip setting adyen_order_payment_id for this function, the downstream operations and payment modifications will suffer from this lacking field.

Best Regards,
Can
