直到现在，我只有一个由Firebase存储上传触发的CF：
export const onAvatarUpload_v1 = functions.storage.object().onFinalize(async (object) => {
// [... something that works, the actual code is at the end of the question]
}
每次客户端将对象上载到存储时，都会触发此功能。如果将此类对象上载到特定文件夹，则指向该资源（头像）的链接将保存到firestore集合中的文档中。
在我定义了一个也由存储上传触发的新CF之前，这很好而且很花哨：
export const onUserPofilePictureUpdate_v1 = functions.storage.object().onFinalize(async (object, context) => {
// something that presumably works, but that I have not been able to try, the actual code is at the end of the question
}
现在，在同时部署两个CF的情况下，这些CF在执行时生成的日志如下所示：
12:52:31.753 p. m.
assetsManagement-onAvatarUpload_v1
Function execution started
12:52:31.764 p. m.
assetsManagement-onAvatarUpload_v1
undefined
12:52:31.768 p. m.
assetsManagement-onAvatarUpload_v1
Function execution took 17 ms, finished with status: 'error'
我还没有测试第二个CF。但是我敢肯定，在部署第二个CF之前，第一个CF可以工作。这就是让我认为可能存在一些限制的原因。
是否正确？通过存储上传可以触发多少个CF是否有限制？ Firebase可能存在错误？没有console.log语句只能是undefined，因为我总是将CF的名称添加到console.log语句中。这表明我的代码甚至无法运行。
编辑：我正在添加两个云函数的代码。
//This is the one that worked until I deployed the other one.

自从我部署了两个功能以来，我在两个功能的日志中看到的唯一输出是：
