成功配置我的 Stripe 和 WSO2 API Manager 帐户后，我为我的 API 创建了动态费率订阅并相应地链接了它。 API 货币化已设置完毕，当我使用 Postman 发送使用数据时，一切都很顺利。但是，在尝试查看发票时，会出现一个弹出窗口，其中显示消息“无可用数据”和“未找到此订阅的待处理发票数据”。
错误：

我最初使用的是4.2.0版本，并尝试多次查看发票但没有成功。后来我切换到4.1.0版本，解决了这个问题。我仍然希望在 4.2.0 版本中找到解决方案。
我对 WSO 或任何其他方面一无所知，但我的猜测是，如果您深入研究这一点，您会发现它与 Stripe API 版本中的更改有关，即要收取发票费用，您首先创建发票对象然后将项目添加到其中；在旧版本中，您首先创建 InvoiceItems，然后创建发票，这会“拉入”浮动项目。
