Question

编写一个创建用户时触发的简单示例函数时出现以下错误。

代码：

exports.createUser = functions.firestore
  .document('users/{userId}')
  .onCreate((snap, context) => {
    const newValue = snap.data();
    const name = newValue.name;
    //....do some stuff here
  });

错误说明：

Error: Cloud function needs to be called with an event parameter.If you are writing unit tests, please use the Node module firebase-functions-fake.
    at Object.<anonymous> (/srv/node_modules/firebase-functions/lib/cloud-functions.js:84:19)
    at Generator.next (<anonymous>)

    at process._tickDomainCallback (internal/process/next_tick.js:228:7)

版本：

“ firebase”：“ ^ 5.3.0”

“ firebase-admin”：“ ^ 5.12.1”

“ firebase-functions”：“ ^ 1.1.0”

只是找不到此代码出了什么问题。新创建用户文档时，我不断收到有关事件的错误。有没有人面对过它，我该如何解决？

Answer 1

您的Firebase依赖项看起来真的很旧。 firebase-admin现在为6.3.0，firebase-functions为2.1.0。确保您的代码针对您真正要使用的这些库的版本使用了正确的API。
