Deploying Cloud Functions for Firebase locally. admin.initializeApp(functions.config())

Question

When I tried to deploy a function on my local firebase emulator, I got this error

ERROR: Function load error: Code could not be loaded.
ERROR: Does the file exists? Is there a syntax error in your code?
ERROR: Detailed stack trace: /home/krishna/whozoo-firebase-web/functions/node_modules/firebase-functions/lib/config.js:51
        throw new Error('Firebase config variables are not available. ' +
Error: Firebase config variables are not available. Please use the latest version of the Firebase CLI to deploy this function.

    at maybeClose (internal/child_process.js:877:16)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:226:5)

Then I retried deploying after removing this particular line of code

admin.initializeApp(functions.config())

My function is deployed successfully but when I hit the endpoint, I end up with this message

{"code": "app/no-app","message": "The default Firebase app does not exist. Make sure you call initializeApp() before using any of the Firebase services."}

How can I solve this error?

EDIT

'use strict';

const admin = require('firebase-admin');
const functions = require('firebase-functions');
const register = require('./register');

admin.initializeApp(functions.config());

exports.register = functions.https.onRequest(register.registerHandler);

register.js

'use strict';

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

cors(req, res, () => {
let requestBody = req.body;

admin.auth().createUser({
        'email': requestBody.email,
        'emailVerified': false,
        'password': requestBody.password,
        'displayName': requestBody.firstName + ' 
        ' +requestBody.lastName
    });
});

This is the part of register.js that I believe causes the problem. The rest of the register.js contains the response message.

According to this post it is not possible yet to deploy a Firebase function locally https://stackoverflow.com/questions/42763951/run-firebase-cloud-functions-locally?rq=1 — louisvno, May 26 '17 at 08:49
Edited the post to include the index.js file. @DougStevenson — Krishnaarjun S, May 30 '17 at 18:42
I've added the register.js module. Does this error occur because admin.auth().createUser() is an API on firebase and this can't be brought down to the local emulator? @DougStevenson — Krishnaarjun S, Jun 01 '17 at 19:29

Instead of this:

admin.initializeApp(functions.config());

Try this:

admin.initializeApp();

Also, put that line before you require your register module.
