[Google Pay] createPaymentRequest results in PaymentError

Start at GooglePayButton.createPaymentRequest and compare the supplied options with the Google Pay example, focusing on the PaymentError statusCode 10. Reproduce the call with the listed NativeScript, Google Pay, Stripe, and Android settings, then verify that the payment sheet appears instead of immediately invoking PaymentError.

I'm basically following the Google Pay example in a Vue app. Calling createPaymentRequest on the GooglePayButton object immediately results in the PaymentError handler being called, with statusCode 10 and statusMessage "10: ". I don't see any other error information being returned. The Google Pay sheet does not appear.
