Can you help me to solve this error about json?

I'm trying to connect Firebase using node.js
I have following code in my json file.
const functions = require('firebase-functions');
const hmac_sha256= require ('crypto-js/hmac_sha256');
const request= require('request');
const admin= require('firebase-admin');
const service_Account= require('./service_account_key.json');
const firebaseConfig= json.parse(process.env.FIREBASE_CONFIG);
firebaseConfig.credential= admin.credential.cert("service_Account");
admin.initializeApp(firebaseConfig);
exports.getCustomToken = functions.https.onRequest((req,res)=>{
const accessToken= req.query.access_Token;
const FacebookAppSec= '72100b8d4ee21a85fc67d014f3b0c9fa';
const AppSecretProof= hmac_sha256(accessToken,FacebookAppSec);
//Validate token...
const uri='https://graph.accountkit.com/v1.1/me?access_Token=${accessToken}&App_Proof=${AppSecretProof}';
request({
url= uri,
json:true
},(error,fbresponse,data)=>{
if(error)
{
console.error('Access Token validation request failed\n',error);
res.status(400).send(error);
}
else if(data.error)
{
console.error('Invalid Access Token\n',
'access_Token=${accessToken}',
'App_Proof=${AppSecretProof}',data.error);
res.status(400).send(data);
}
else
{
admin.auth().createCustomToken(data.id)
.then(CustomToken => res.status(200).send(CustomToken))
.catch(error => {
console.error('Create Custom Token Failed.',error);
res.status(400).send(error);
})
}
})
})

I see many answers on stack overflow as well as on github, but nothing proceed. i have tried my best to solve it by myown also get help from online community but now posting this to all of you.

The output shows that ESLint is giving you this error message on line 19 of index.js:
19:9 error Parsing error: Shorthand property assignments are valid only in destructuring patterns
Line 19 is url= uri below:
request({
url= uri,
json:true
},(error,fbresponse,data)=>{
If you want to give values to properties in a JavaScript objects, you have to use : instead of =, just like you did with json:true.
request({
url: uri,
json:true
},(error,fbresponse,data)=>{

How to fix "Test suite failed to run" when running a test with jest

I'm learning how to write tests with jest and I'm getting this huge log exit when I run them.
Since it's a tiny code, I see no problem in posting it entirely.
describe('First test', async () => {
const OLD_ENV = process.env;
beforeEach(() => {
jest.resetModules();
process.env = { MONGO_CLUSTER_URI: <<<hidden for security reasons>>>' };
})
afterEach(() => {
process.env = OLD_ENV;
})
test('Should pass', async () => {
console.log('Testing...');
const response = await index.handler({ event: 'input' }, { });
console.log(response);
expect(response).toBe(true);
})
})
I don't know if it's supposed get me such a big output, but i think it's not since it looks like it's throwing some kind of error. I'm posting the output below so you guys can help me.

The first line of your test should be
describe('First test', () => {
The error is telling you what the issue is. Basically, describe shouldn't be asynchronous, because multiple describes or tests within them will run concurrently.

How to fix error "npm ERR! missing script: start"

I am getting the following error:

Your JSON is invalid. you just need a comma after the script curly bracket which is just after the start script

I keep getting "Failed to load resource" when I try to start an React app

So I'm working on a React App using Webstorm for IDE. As far as I can tell everything seems to be configured properly, but somehow when I try to run the app it would throw an error "Failed to load resource: the server responded with a status of 404 (Not Found)".
Here is a sample of script in the index:
<script>
try {
Typekit.load({
async: true
});
} catch (e) {}
</script>
<script type="text/javascript" src="app/fonts/Numbers.js"></script>
<script src="/dist/app.bundle.js"></script>
...From server.js
const express = require('express');
const path = require('path');
const fs = require('fs');
const bodyParser = require('body-parser');
const app = express();
const renderIndex = function (req, res) {
console.warn(__dirname + '/app/' + 'index.tpl.html');
res.sendFile(path.join(__dirname, '/app/', 'index.tpl.html'));
};
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
app.use(express.static(path.join(__dirname, '/')));
app.listen(3000, function () {
console.log('Your app listening on port 3000!')

What I want to accomplish is to have the app run in the browser, but continue getting an error. A response will be very much appreciated. Thanks.

Have you tried removing the first forward slash from the path
src='dist/app.bundle.js'

Are you able to confirm that the entry point path is indeed correct? "/dist/app.bundle.js"

Maybe you could add server route / which returns your index html
app.get('/',function (req, res) { res.sendFile(pathToYourHTML) })

Webpack npm-debug.log file issue

I have installed webpack for my project. However, when I try to run a command to convert scss in to css i get an error that says "Please include the following file with any support request: C:\wamp\www\chandco\wp-content\themes\chandco\npm-debug.log".
The thing is this file already exists so I;m confused where the problem is.
Any help will be appreciated.
Thanks.
