Cloud Functions 出现 Firestore 错误 "Deadline Exceeded"

Question

我目前正在测试新的 firestore，但我总是遇到同样的问题，它告诉我一些关于 Deadline exceeded

{ Error: Deadline Exceeded
    at /user_code/node_modules/firebase-admin/node_modules/grpc/src/node/src/client.js:554:15
  code: 16,
  metadata: Metadata { _internal_repr: {} },
  note: 'Exception occurred in retry method that was not classified as transient' }

这是我当前的代码，看起来不错（并且在我将其部署到 Firebase 时有效）

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

const admin = require('firebase-admin');
var serviceAccount = require("./xxxxxxxx-firebase-adminsdk.json");

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: "https://xxxxxxxxx-xxxx.firebaseio.com"
});

exports.registerUser = functions.auth.user().onCreate(event => {
  admin.firestore().collection('users').doc(event.data.uid).set({
    name: 'Test User',
    country: 'USA'
  }).catch(error => {
    console.log(error);
  })
});

它还显示此消息函数返回未定义、预期的 Promise 或值

Answer 1

使用 Cloud Functions 触发器，您需要 return a promise 在工作完成后解决。文档中的 set() 方法 return 是一个承诺，因此您应该 return 让 Cloud Functions 知道何时可以安全地清理该函数：

exports.registerUser = functions.auth.user().onCreate(event => {
  return admin.firestore().collection('users').doc(event.data.uid).set(...)
});
