Javascript 您使用什么数据类型将字典传递到HttpScalable函数？

我不熟悉服务器端代码，我一直在尝试将数据库文档创建切换到服务器端进行帐户创建。下面我介绍了我在xcode项目中定义的函数以及服务器端函数。调用函数后，我得到一个错误

未处理的错误：参数“data”的值不是有效的Firestore文档。无法将“undefined”用作Firestore值（在字段“First_Name”中找到）。如果要忽略未定义的值，请启用

ignoreUndefinedProperties

---

仔细阅读错误消息。它只是告诉您，您为新文档的First_Name属性提供的值未定义。这只意味着你没有为你的应用程序中的一个字段提供值。因为我们无法在你的应用程序中看到

self.userFN

的价值，所以我们不知道这里到底发生了什么

---

我建议您在客户端应用程序和后端功能上进行一些日志记录，以查看实际发送和接收的数据，这样您就可以诊断呼叫是否按预期方式进行。

所有字段的值都正确存储在我的项目中，并且可以在客户端访问。我已经包含了上面描述的代码。我在这里没有看到任何有用的调试信息。请添加一些日志，显示此代码的执行方式以及客户端和后端上使用的值，以便我们可以看到发生了什么。我在上面包含了更多的代码。在我的代码中，我将用户提供的值存储在字典中，并最终使用字典生成RegistrationModel类的实例。我在typescript的底部包含了服务器端代码，我在调试器中运行了该代码，并且能够看到rm变量中正确存储的值
