Running Purchase Anon on Subscription Errors

[CoPokBl]

When attempting to purchase a subscription anonymously, the server doesn't handle it and Stripe errors:

      An unhandled exception has occurred while executing the request.
      Stripe.StripeException: You specified `payment` mode but passed a recurring price. Either switch to `subscription` mode or use only one-time prices.
