Runnig the challenge locally isn’t working for submission. I’ve passed all the necessary tests locally, so i keep the server running and tried to paste the localhost:3000 but it fails the FCC check.

do you have any error in the browser console on the freecodecamp page?
Actually yes. Here is a screenshot of the last try.

cors errors
you need to add the cors module
see for the cors module for example
You are getting CORS blocked. Move the cors middleware up right below var app = express();
var app = express();
var cors = require('cors');
app.use(cors({optionsSuccessStatus: 200})); // some legacy browsers choke on 204
You are not using toUTCString in the GMT condition for the UTC time.
Hello @ILM ,
I found out from the link you shared with me, that the CORS header is missing.
i have managed to successfully submited the link and passed all 5 tests with this addition to the code.
'use strict';
require('dotenv').config();
const express = require('express');
const myDB = require('./connection');
const fccTesting = require('./freeCodeCamp/fcctesting.js');
const app = express();
// add this CORS header
app.use((req, res, next) => {
res.header('Access-Control-Allow-Origin', '*'…
Thanks for the share. I think i do it right, but it’s still not working, getting the same console error messages.
Here is the code. And the previous version is on my github freeCodeCamp/quality-assurance at main · PedroBizachi/freeCodeCamp · GitHub cloned from the boilerplate.

try with the options for the cors module too, adding the cors headers
I’ve tryed, without success.
I’m going to close this forum because switching browsers was my only option. I was using Chromium, but I switched to Firefox and now I can submit my lessons.
