Voiding partial refunds does not work for Stripe payment method (both SCA and Connect)

[filipefurtad0]

Description

Voiding of the initial payment of an order is possible for Stripe (SCA and Connect). If a partial refund has been issued, this is currently only possible for Stripe-Connect, this fails for Stripe-SCA (see issue #5829).

This issue reports on the existing bug concerning the voiding of partial refunds, after these were issued - This is currently not working for Stripe-SCA. It's not working for Stripe-Connect either, but this payment methods will be eventually discontinued.

Expected Behavior

Voiding partial refunds should be possible for Stripe SCA and Connect payment methods.

Actual Behaviour

Attempting to void a partial Stripe payment shows an error and does not cancel the refund (both SCA and Connect).

Steps to Reproduce

Customer (or Admin, in the BO)

1. Place two orders with several items, using Stripe-SCA in one and Stripe-Connect in the other, as a payment method.

Admin
2. Edit the respective order, remove some items.
3. Go to Payments - there should be a given amount in credit owed.
4. Press "Credit" on the initial payment of the order. A second entry should appear under Payments.
5. Press the X (void) of the refund payment. See one of the messages below, for the respective payment method.

Workaround

For Stripe-Connect a workaround may be to issue a full refund, cancel the order, and start over. This is not possible at the moment for SCA, but cancelling the order is.

Update: the shop may issue a new payment on that order and get that money back to the customer.

Severity

bug-s3: a feature is broken but there is a workaround

Your Environment

• Version used: v3.1.3
• Browser name and version: Firefox 78
• Operating System and version (desktop or mobile): Desktop Ubuntu 20.04

Possible Fix

I guess it is debatable whether a fix for this should necessarily involve both payment methods - probably not, as Stripe-Connect will be eventually discontinued. So I guess the fix should focus on Stripe-SCA.

I'd say this is an S4. On StripeSCA, users can issue a new payment on the order to get that money back to the customer. A refund in StripeSCA is anyway a new credit payment.

Good point @luisramos0,
updated the Workaround section above.

But I guess for this workaround the shop/admin will need the customers credit card data, right?
