Hello @jonathanribas. Thanks for the detailed report.

Could you share the lines related to this order, capture and refund from var/log/adyen/info.log? My guess is that the refund response is not including the pspReference for you.

Hi @acampos1916,

Thanks. Could you also share the response from info.log? Should be right after the 2021-08-02 16:48:48 line @jonathanribas

@acampos1916, here you go sorry: [2021-07-29 00:05:37] AdyenLoggerTest.INFO: JSON Response to Adyen:{"additionalData":{"pspref":"1856275170911475","klarnapayments.session_id":"c7bf8d40-c681-435a-b18c-fc2c08119224","acquirerAccountId":"1258359"},"pspReference":"1856275170911475","resultCode":"Authorised","amount":{"currency":"USD","value":9548},"merchantReference":"82000404328"} {"is_exception":false} []

Thanks for the log lines @jonathanribas. Then this could be related to the line item count while adjusting the refund amount. I've opened an internal ticket to look into it.

[jonathanribas]

Hi @acampos1916, we also have this issue for partial refunds on Credit Cards, it's becoming a serious issue for us with big impact on Customer Service. Do you think you guys could dig into it soon? Thanks!

[cyattilakiss]

Hi @jonathanribas ,

We are going to start working on this ticket in our next sprint which starts next week Monday. We are going to keep you updated.

Best, Attila Adyen

[jonathanribas]

Hi @cyattilakiss, thanks for the update!

[Morerice]

Hi @jonathanribas,

Apologies for our delay. We have been trying to recreate the problem by following the steps to reproduce, on Magento v2.3.7 and Plugin version v7.0.1, but unfortunately we weren't able to reproduce the same outcome.

Attached are two screenshots showing the inputs for the refund screen and the result page. Please note that the error shown in the result page was fixed in https://github.com/Adyen/adyen-magento2/pull/1055.

Could you confirm if the inputs for the refund screen are identical to yours and if not could you highlight what you are doing differently?

Best regards, Jean Adyen

[jonathanribas]

Hi @Morerice,

Thanks for the update!

Before opening this issue, we've already applied #1055 patch on our Adyen 7.0.1. We also set quantity to refund as 0 as your print screen and we have this PSP Reference issue.

Best regards, Jonathan.

This issue is also happening on adyen 7.1.0. Reproduced it for Clearpay.

When 'dumping' the $response, on vendor/adyen/module-payment/Gateway/Response/PaymentRefundDetailsHandler.php Response is an error: Invalid amount specified

Linking issue https://github.com/Adyen/adyen-magento2/issues/982

[tnaber]

Thank you @manuel-EGO for recreating the bug for a different payment method and linking a related issue. I managed to verify the issue (in 7.3.0) when the refund value is set to 0, this created the same error as indicated by @jonathanribas. However, I did not get the 'Invalid amount specified'. Could verify if this is indeed the same use case?

An internal ticket has been created which will be picked up shortly.

[manuel-EGO]

Hi @tnaber the error displayed on the top of the page is the same error @jonathanribas reported, but dumping the $response on module-payment/Gateway/Response/PaymentRefundDetailsHandler.php outputs the error: Invalid amount specified.

[tnaber]

@manuel-EGO so I'm right in assuming that you are trying to do a refund with a refund value of 0? Out of curiosity, why would you want to do that?

[manuel-EGO]

Hi @tnaber you are almost right, I am trying to refund an order, not refunding any items, but adding an adjustment refund. I have a link of a video of the issue but it has some sensitive data, can I send you the video in any other way? (I rather not put the url here)

[tnaber]

You can mail it to !

[manuel-EGO]

ty @tnaber email sent, many thanks

[tnaber]

@manuel-EGO, @jonathanribas #1213 should resolve this issue, feel free to add a review to the PR :) Let me know if this works for you!
