c# - 无法在沙盒中立即向无卡客户收费

Question

问题是我无法立即在沙盒帐户中向无卡客户收费。一旦我通过 .net sdk 创建付款，它会在 6 天后自动设置收费日。下面我如何为客户创建新的无卡支付：

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收费日期时：

            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，我找不到任何有关如何为沙盒明确设置 next_possible_customer_charge_data 的信息。有人整理吗？
