Describe your issue in detail here.
Hi there.

I think I am connected correctly to MongDB but I don’t know how to solve the following error. Somebody please help me :slight_smile: thanks in advance

Your code so far
// #5
myDB(async (client) => {
const myDataBase = await client.db(‘database’).collection(‘users’);

app.route(’/’).get((req, res) => {
res.render(‘pug’, {
title: ‘Connected to Database’,
message: ‘Please login’
});
});

passport.serializeUser((user, done) => {
done(null, user._id);
});
passport.deserializeUser((id, done) => {
myDataBase.findOne({ _id: new ObjectID(id) }, (err, doc) => {
done(null, doc);
});
});
}).catch((e) => {
app.route(’/’).get((req, res) => {
res.render(‘pug’, { title: e, message: ‘Unable to login’ });
});
}).catch((e) => {
app.route(’/’).get((req, res) => {
res.render(‘pug’, { title: e, message: ‘Unable to login’ });
});
});
