android - 功能部署错误 Firebase

Question

我尝试在 firebase 函数上发布简单代码，但每次都会产生错误

errors
functions: Finished running predeploy script.
i  functions: ensuring necessary APIs are enabled...
✔  functions: all necessary APIs are enabled
i  functions: preparing functions directory for uploading...
i  functions: packaged functions (53.73 KB) for uploading
✔  functions: functions folder uploaded successfully
i  functions: updating function sendNotification...
⚠  functions[sendNotification]: Deployment error.
Error setting up the execution environment for your function. Please 
try again after a few minutes.


 Functions deploy had errors. To continue deploying other features (such as database), run:
  firebase deploy --except functions

Error: Functions did not deploy properly. 

我尝试部署的代码是

'use strict'

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);




exports.sendNotification = functions.database.ref('/notifications/{user_id}/{notification_id}').onWrite(event => {




 const user_id = event.params.user_id;
 const notification_id = event.params.notification_id;

 console.log('We have a notification from : ', user_id);

 });

面对这个错误大约 2 天尝试堆栈和其他论坛上可用的所有答案，但能够找到任何人可以帮助我的解决方案

Answer 1

您应该让您的函数返回值、null 或 promise 。除此之外，我看不出有什么不妥。您似乎得到的错误可能是您这边的连接问题，或者(奇怪的是)Google 的 Firebase 方面的问题。

同时尝试更新您的 Firebase 工具

npm install -g firebase-tools

啊，考虑一下这里的更新以进行一些小的更改，因为云功能不再处于测试阶段: https://firebase.googleblog.com/2018/04/launching-cloud-functions-for-firebase-1-0.html?utm_source=email&utm_medium=email&utm_campaign=cloud_functions_v1.0
