我是服务器端代码的新手，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。下面我包含了我在xcode项目中定义的函数以及服务器端函数。调用函数后，我收到一个错误，说
未处理的错误错误：参数"的值；数据"；不是有效的Firestore文档。不能使用"；未定义的"；作为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属性提供的值是未定义的。这只是意味着你没有为应用程序中的那个字段提供值。由于我们在您的应用程序中看不到self.userFN的值，我们真的不知道这里发生了什么。
我建议您在客户端应用程序和后端功能上进行一些登录，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。
