Hi
When creating the Payment Element, try setting postalCode to auto
https://stripe.com/docs/js/elements_object/create_payment_element#payment_element_create-options-fields-billingDetails-address-postalCode

Otherwise, you can collect billing address using Address Element:
https://stripe.com/docs/elements/address-element
So that you are sure to collect all the required fields you need

Thanks for the answer.
I have tried adding postalCode like this:

elements.create('payment', {
  fields: {
    billingDetails: {
      address: {
        country: 'auto',
        postalCode: 'auto',
      },
    },
  },
})

But no avail. I guess I can explore the address element more.
