Validation failure with default billing address and Mollie credit card selected

[avstudnitz]

When clicking "Place Order", it doesn't submit the order, but instead scrolls up to the address selection.

Prerequisites

• Mollie Creditcard is selected
• Customer logged in, having a default billing address
• The initial address isn't changed
• Virtual order (might not be a prerequisite, haven't tested otherwise)
• Onepage layout (might not be a prerequisite, haven't tested otherwise)

Additional notes

• It works for prepayment and Mollie Paypal. This is independent of which payment method was preselected or selected before.
• it works after I selected another address. It doesn't seem to depend on the address itself, it's only important that it hasn't been changed. It also works if I select another address and then the initial address again.
• It could have to do with the frontend validation.
• No messages in the JS console or in the log files.
• The last AJAX call goes out to /magewire/post/livewire/message/checkout.payment.method.mollie_methods_creditcard, executing the setCardToken method. It returns successfully. After that, the window scrolls up. The call seems to be executed in the vendor/mollie/magento2-hyva-checkout/src/Mollie_HyvaCheckout/view/frontend/templates/component/payment/method/creditcard.phtml file.
• If I disable the lines https://github.com/mollie/magento2-hyva-checkout/blob/main/src/Mollie_HyvaCheckout/view/frontend/templates/component/payment/method/creditcard.phtml#L48-L64, it works. But, as the token isn't set, mollie shows me a form where I can enter my CC number instead of using the number I entered in the checkout.
• I also tested switching to the default theme and removing all customization for the checkout - no change.

Hi There @avstudnitz ,

We’re actively working on this issue, but it could also be related to the Hyvä checkout or Magewire. We’re investigating this internally and will also reach out to the Hyvä team (you, I noticed now ;-)) to help pinpoint the cause. We’ll get back to you shortly!

[avstudnitz]

I just double-checked on https://checkout-demo.hyva.io/ - same effect, you cannot checkout in that case.
