How to Fix Express Routing

Question

router.post('/login', (req, res, next) => {

  User.findOne({ "email": req.body.email }, (err, user) => {
    if (err) throw err;

    if (!user){
        res.json({
            success: false,
            message: 'Authenticated failed, User not found'
        });
    } else if (user) {

        var validPassword = user.comparePassword(req.body.password);
        if (!validPassword) {
            res.json({
                success: false,
                message: 'Authentication failed. Wrong Password'
            });
    } else {
        var token = jwt.sign({
            user: user
            }, config.secret, {
                expiresIn: '7d'
            });

            res.json({
                success: true,
                message: "enjoy your token",
                token: token
            });
        }
    }

});

Error:

events.js:180 throw err; // Unhandled 'error' event ^ Error [ERR_UNHANDLED_ERROR]: Unhandled error. (Incorrect arguments) at Function.emit (events.js:178:17) at C:\Users\farid\Desktop\Ecomerce\server\node_modules\mongoose\lib\model.js:4640:13 at C:\Users\farid\Desktop\Ecomerce\server\node_modules\mongoose\lib\query.js:4345:12 at process.nextTick (C:\Users\farid\Desktop\Ecomerce\server\node_modules\mongoose\lib\query.js:2841:28) at process._tickCallback (internal/process/next_tick.js:61:11)

I don't know what I am missing, can someone highlight the error in the code?

Use try catch block in your code hope this will help you.
