无法立即在沙盒中向无门禁客户收费

Question

问题在于，我无法立即在沙盒帐户中向无门禁客户收取费用。通过.net sdk创建付款后，它会自动在6天后设置收费日。下面是我如何为客户创建新的无密码支付方式：

var createResponse = await _goCardlessClient.Payments.CreateAsync(new PaymentCreateRequest()
        {
            Amount = 10,
            Currency = PaymentCreateRequest.PaymentCurrency.GBP,
            Links = new PaymentCreateRequest.PaymentLinks()
            {
                Mandate = "mandateId goes here",
            },
            Metadata = new Dictionary<string, string>()
            {
                { metadata goes here }
            },
            IdempotencyKey = Guid.NewGuid().ToString()
        });

当我尝试通过以下方式明确设置充电日期时：

            var createResponse = await _goCardlessClient.Payments.CreateAsync(new PaymentCreateRequest()
        {
            Amount = 10,
            Currency = PaymentCreateRequest.PaymentCurrency.GBP,
            ChargeDate = DateTime.UtcNow.ToString("yyyy-MM-dd"),
            Links = new PaymentCreateRequest.PaymentLinks()
            {
                Mandate = "mandateId goes here",
            },
            Metadata = new Dictionary<string, string>()
            {
                { metadata goes here }
            },
            IdempotencyKey = Guid.NewGuid().ToString()
        });

我得到一个例外说：

  

charge_date必须在授权的next_possible_customer_charge_date或之后

在官方文档中，我找不到有关如何为沙箱显式设置next_possible_customer_charge_data的任何信息。有人解决吗？
