Node JS Require throw AssertionError: missing path

I'm stuck on a problem for a few hours, but cannot find it out.
I've a simple application write in node js:

var mongo = require('./helpers/mongo_utils.js');
var express = require('express');
var user = require('./models/users.js');

mongo.connect(function (err)
{
if (err) throw err;
console.log('connected');

var app = express();
app.listen(3000, function ()
{
console.log('Server set up and start listening on port 3000');
})
})


All works except when i require the users.js file. If I don't require it i have no problem, but when i do it i got this error:

assert.js:89
throw new assert.AssertionError({
^

If someone can help me with this it would be wonderful !!

Here is the code of users.js if it can help:

var mongo = require('') = ('./../helpers/mongo_utils.js');
var mailValid = require('./../helpers/email_valid.js');

var db = mongo.getDb();

var User = function (pseudo, psw, mail, level, callback)
{
// Params checking
if (!(pseudo && psw && mail && (level != 'undefined')))
{
err = new Error("All fields aren't specified"); err.code = 0;
return callback(err);
}
// Mail validation
if (!mailValid(mail))
{
err = new Error("Mail adress isn't valid"); err.code = 1;
return callback(err);
}
db.users.findOne({mail: mail}, function (err, doc)
{
if (err) throw err;
if (doc)
{
err = new Error("Mail adress already used");
err.code = 1;
return callback(err);
}
});

// Pseudo
if (!(pseudo.length > 0 && pseudo.length < 20))
{
err = new Error("Pseudo length invalid");
err.code = 2;
return callback(err);
}
db.getDb.users.findOne({_id: pseudo}, function (err, doc)
{
if (err) throw err;
if (doc)
{
err = new Error("pseudo déja utilisé"); err.code = 2;
return callback(err);
}
});

// Psw validation
if (!(psw instanceof String))
{
err = new Error("Password invalid"); err.code = 3;
return callback(err);
}

// Level validation
if (!(lvl > 0 && lvl < 10))
{
err = new Error("Access level invalid"); err.code = 4;
return callback(err);
}

// If all test are OK, we construct and instance of User and pass it to the callback
else
{
this.pseudo = pseudo;
this.psw = psw;
this.mail = mail;
this.date = Date.now();
this.lvl = lvl;
return callback(null, this);
}
}

module.exports = User;

Answer

Read the stacktrace:

This is wrong:

var mongo     = require('') = ('./../helpers/mongo_utils.js');

Not sure what you are trying to achieve, but should probably be this instead:

var mongo     =  ('./../helpers/mongo_utils.js');
