Serialization of a Passport User -> 'Database connection should be present' fails

Tell us what’s happening:

No matter what I try, no matter how many posts I’ve read, I cannot get my challenge to pass the Database connection should be present check (the other test passes).

Note that I’m using the replit.com site to do my challenges, so I’ve also set up the security of the MongoDB to allow for “universal” access until this challenge is complete.

The app appears to run just fine within the replit site, and produces this output:

Here’s my code:

"use strict";
require('dotenv').config();

const express = require("express");
const fccTesting = require("./freeCodeCamp/fcctesting.js");

const session = require("express-session");
const passport = require("passport");
const mongo = require('mongodb').MongoClient;

const app = express();

fccTesting(app); //For FCC testing purposes
app.use("/public", express.static(process.cwd() + "/public"));
app.use(express.json());
app.use(express.urlencoded({ extended: true }));

fccTesting(app); //For FCC testing purposes

app.set("view engine", "pug");
app.route("/").get((req, res) => {
  res.render(process.cwd() + '/views/pug/index', { title: 'Hello', message: 'Please login' });
});

app.use(session({
  secret: process.env.SESSION_SECRET,
  resave: true,
  saveUninitialized: true,
}));

app.use(passport.initialize());
app.use(passport.session());

mongo.connect(process.env.DATABASE, {useUnifiedTopology: true, useNewUrlParser: true}, function(err, db){
  if (err) return console.log(err);
  console.log('Successful database connection')
  passport.serializeUser(function(user, done){
    done(null, user._id);
  });
  passport.deserializeUser(function(id, done){
    db.collection('users').findOne({_id: new ObjectID(id)}, function(err, doc){
      if (err) return console.log(err);
      done(null, doc);
    })
  });

  app.listen(process.env.PORT || 3000, () => {
    console.log("Listening on port " + process.env.PORT);
  });
});

I had the same problem
the issue was is the title variable
