424 Error & “Payment not completed” with Apple Pay in shopify SDK

[peng1]

I always got the error "Payment not completed" with Apple Pay  with the real card.

Here is the payment setting:

When I debuged the code , I have got the payment code from apple pay, and then failed to pay with the error from Shopify SDK API.

Here is the error infomation from the sdk API : (- (NSOperation *)updateCheckout:(BUYCheckout *)checkout completion:(BUYDataCheckoutBlock)block) .

Error Domain=BUYShopifyErrorDomain Code=424 "(null)" UserInfo={errors={

    checkout =     {

        "payment_gateway" =         (

                        {

                code = "processing_error";

                message = "Your payment could not be processed at this time, please try again in a few minutes";

                options =                 {

                    "raw_gateway_error" = "There was an error processing your payment. Please try again.";

                };

            }

        );

    };

}}

So what  should I do to solve the problem.

Thanks.
