Hello,

Yes, I was able to reproduce it and capture the JavaScript stack.

The error is triggered here:

const { payment_method } = result.paymentIntent;

if (['promptpay', 'swish', 'paynow', 'cashapp'].includes(payment_method.type)) {

The problem is that, after cancelling the MB WAY payment in the app, the returned PaymentIntent has:

"status": "requires_payment_method",
"payment_method": null

while the response still includes the failed payment method under:

"last_payment_error.payment_method.type": "mb_way"

So the frontend tries to read payment_method.type even though payment_method is null, which causes:

Cannot read properties of null (reading 'type')

This appears to be a null-handling issue in the plugin/frontend when a customer cancels an MB WAY payment via UPM.

I am attaching the debugger screenshot and the relevant PaymentIntent payload.
