Firebase 函数正在部署，但未显示在控制台中

Question

This question is essentially the same as question 44799104 , only that I provide my index.js (and the only answer there was not helpful, as I do include 'exports').

In short, I have deployed my function successfully,

but it does not show in the console. Where am I going wrong? Here is my index.js:

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

admin.initializeApp(functions.config().firebase);

var delayInMilliseconds = 5000;


exports.copyRoom= functions.database.ref('/RoomsOwn/${AuthUid}').onWrite((event) => {

    var uid = event.params.AuthUid;
    console.log('AuthID: ' + uid);
    var object = event.data.val();
    console.log('Whole Object: ', object);

    setTimeout(function() {
    return admin.database.ref('/RoomsOthers/${uid}').set(object);
    }, delayInMilliseconds);

  });

Answer 1

You didn't actually deploy that function when you ran firebase deploy . If you had successfully deployed it, the name of the function would have appeared in the Firebase CLI output.

Make sure you:

1. Actually saved the file with the function you're trying to deploy.
2. The file is in the correct directory. For JavaScript projects, the default is functions/index.js
3. Are deploying the correct project from the correct directory.

Answer 2

In my case I just had to cd into the functions folder before deploy. Note that you should be getting this in your output:

Answer 3

For me the problem was in the name of the function. My function name was fooBar but I was using foobar .

firebase deploy --only functions:foobar // Incorrect
firebase deploy --only functions:fooBar // Correct
