Estoy tratando de hacer un conector roblox mongodb, pero la conexión no funciona correctamente. Dice MongoError: bad auth : Authentication failed. cada vez que lo intento.

Aquí está mi código

 const express = require('express') const app = require('express')() const bodyParser = require('body-parser'); const mongoose = require("mongoose") const username = process.env.USERNAME const passwordAuth = process.env.PASSWORD const mongoPass = process.env.MONGO_PASS const mongoUser = process.env.MONGO_USER mongoose.connect(`mongodb+srv://${mongoUser}:${mongoPass}@cluster0.i3et1.gcp.mongodb.net/testing?retryWrites=true&w=majority`, {useNewUrlParser: true, useUnifiedTopology: true }); var db = mongoose.connection; db.on("error", console.error.bind(console, "connection error:")); db.once("open", function() { console.log("Connection To MongoDB Atlas Successful!"); }); app.use(express.json()); app.use((req, res, next) => { const auth = {login: username, password: passwordAuth} // parse login and password from headers const b64auth = (req.headers.authorization || '').split(' ')[1] || '' const [login, password] = Buffer.from(b64auth, 'base64').toString().split(':') // Verify login and password are set and correct if (login && password && login === auth.login && password === auth.password) { // Access granted... return next() } res.set('WWW-Authenticate', 'Basic realm="401"') res.status(401).send('Authentication required.') })

He comprobado mongo_user y mongo_pass muchas veces, y son exactamente idénticos a mi usuario y mi pase.
