Stripe Subscription incomplete after 3DS check

Question

I'm not sure I understand this "new" Stripe SCA 3DS flow. When I successfully complete the 3DS authentication, create a customer, then the subscription, the subscription is marked as "incomplete".

This is my current Javascript implementation:

form.addEventListener('submit', function(event) {

    event.preventDefault();
    disableFormSubmit(true);

    stripe.confirmCardPayment($('input#client_secret').val(), {

        payment_method: {
            card: cardElement,
            billing_details: {
                name: $('input#first_name').val()+' '+$('input#last_name').val(),
                email: $('input#email').val(),
            }
        }

    }).then(function(result){

        console.log(result);

        if (result.error) {
            disableFormSubmit(false);
            showPaymentError(result.error.message);
        } else {
            if (result.paymentIntent.status === 'succeeded') {
                disableFormSubmit(true);
                $('input#payment_method').val(result.paymentIntent.payment_method);
                form.submit();
            }
        }

    });
});

confirmCardPayment already takes care of the validation, showing me this overlay, where I click "Complete Authentication".

Following this, the customer (and payment method) is successfully created and a subscription is attached to the customer. But the subscription status now says "incomplete" with "requires_action". Now this is what I don't understand. Isn't the previous overlay responsible for this? According to the docs (https://stripe.com/docs/billing/subscriptions/set-up-subscription#manage-sub-status) I should call confirmCardPayment again, which I do not understand as I just did that, see JS code.

Why is my subscription still incomplete with a "requires_action" status even though I literally just completed this step?

The part of the guide you're looking at is about handling additional authentication actions and recovering from failed payments. You should only be providing the client_secret at this point:

stripe.confirmCardPayment(client_secret)

In your code snippet, you're providing the cardElement again, when it was already provided earlier:

stripe.createPaymentMethod({
  type: 'card',
  card: cardElement, // <-------
  billing_details: {
    email: '[email protected]',
  },
})

I suspect something unexpected is happening because of this, so adjust your code to follow the flow of the guide and it should work.
