Cloud Functions Firebase v1.0 won't initialize

Question

With the latest update of firebase cloud functions, I am getting errors while initializing app, as well as database ref.

First Error: Following should work based on Firebase functions v1.0 documentation and samples ( https://github.com/firebase/friendlychat-web/blob/master/cloud-functions/functions/index.js )

const functions = require('firebase-functions'); 
const admin = require('firebase-admin'); 
admin.initializeApp(); //this fails

I get following error on firebase deploy for above code:

Error: Error occurred while parsing your function triggers.

Error: Failed to parse app options file: Error: ENOENT: no such file or directory, open '[object Object]'

    at Object.Module._extensions..js (module.js:654:10)
    at Module.load (module.js:556:32)

This error is resolved if I pass the config file (but it goes against the firebase documentation)

const functions = require('firebase-functions');
const admin = require('firebase-admin');
var config = {
    apiKey: "<APIKEY>",
    authDomain: "<DOMAIN>",
    databaseURL: "<URL>",
    projectId: "<PROJECTID>",
    storageBucket: "<BUCKET>",
    messagingSenderId: "<ID>"
  };
admin.initializeApp(config);//this works

Second Error:When I make database ref call as below , it fails and gives error:

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

var config = {
    apiKey: "<APIKEY>",
    authDomain: "<DOMAIN>",
    databaseURL: "<URL>",
    projectId: "<PROJECTID>",
    storageBucket: "<BUCKET>",
    messagingSenderId: "<ID>"
  };
  const app = admin.initializeApp(config);

  exports.updateUserProfile = functions.database.ref('/UserProfile/{userid}')
    .onCreate((snapshot, context) => {
        console.log(snapshot.val());
    });

Logs:

Running command: npm --prefix "$RESOURCE_DIR" run lint

Please edit the question to show the complete and minimal code that's failing (not any modified code that works). — Doug Stevenson
@DougStevenson Thanks for your reply Doug. I have updated the question — Mohit Juneja
for the sake of other users, can I suggest making the title of your question more descriptive? Cloud Functions Firebase v1.0 is a bit general. Can't config Cloud Functions Firebase v1.0 or Cloud Functions Firebase v1.0 won't initialize will make it easier for others to scan in case they have the same problem. — JP Lew
I was getting the same errors as you and this answer allowed me to deploy. — S Q

You are experiencing this error because of a bug in firebase CLI version 3.18.1. Try uninstalling the current version and install 3.18.0 and this should solve the error.

npm uninstall -g firebase-tools
npm install -g [email protected]

UPDATE: Firebase CLI version 3.18.2 has been released and the issue is now resolved.
