Question

我创建了一个云函数“ createUser”，该函数将在每次在firestore中写入新用户时触发。数据写入成功，云功能也被触发。但这给我一个错误，未定义“ userId”通配符。我将esLint包含在我的项目中，但我认为这无关。

这是index.js代码

const functions = require('firebase-functions');
const admin = require('firebase-admin');

admin.initializeApp();

exports.createUser = functions.firestore
    .document('users/{userId}')
    .onCreate((snap, context) => {
    // Get an object representing the document
     // e.g. {'name': 'Marie', 'age': 66}
     const newValue = snap.data();

     // access a particular field as you would any JS property
     const name = newValue.name;

    // perform desired operations ...
});
