Sending a CardPresentRoutingOption Preference will fail in unsupported markets

Summary

Setting a CardPresentRoutingOption for a on-device generated PaymentIntent will cause an error-message, if the account in question tied to a non-supported country.

  "payment_method_options": {
    "card_present": {
      "routing": {
        "requested_priority": "domestic"
      }
    }
  },

will work fine for a Stripe Account in Germany, but not for one in Portugal.

After experimentation, I can say that this seems to be tied to the Stripe Account country rather then the terminal's location.

In my opinion this code path should never fail and just fall back to the international priority instead of causing a hard 400 parameter_unknown (Received unknown parameter: payment_method_options[card_present][routing])

Code to reproduce

        val params = PaymentIntentParameters.Builder(
                amount = (receipt_total * BigDecimal("100.00")).toLong(),
                currency = event_currency.lowercase(),
                captureMethod = CaptureMethod.Automatic,
                allowedPaymentMethodTypes = getPaymentMethodTypes()
        )
            .setDescription(desc)
            .setStatementDescriptor(desc.substring(0, min(desc.length, 22)))
            .setMetadata(
                mapOf(
                    "app" to "pretixPOS",
                    "appversion" to BuildConfig.VERSION_NAME,
                    "organizer" to conf.organizerSlug,
                    "event" to event_slug,
                    "posid" to conf.devicePosId.toString(),
                    "posserial" to conf.uniqueSerial!!,
                    "receipt" to receipt_id.toString()
                )
            )

                params.setPaymentMethodOptionsParameters(
                    PaymentMethodOptionsParameters.Builder()
                        .setCardPresentParameters(
                            CardPresentParameters.Builder()
                                .setRouting(
                                    CardPresentRoutingOptionParameters(RoutingPriority.DOMESTIC)
                                )
                                .build()
                        )
                        .build()
                )
