Cannot insert into mysql from node js

I have found some replies but I don't understand how to get the solution to my problem.

db.js

var mysql = require('mysql');

var connection = mysql.createConnection({
    host: 'localhost',
    user: 'root',
    password: 'dbuser',
    database: 'voley_db'
});

module.exports = connection;

registroRoute.js

var express = require('express');
var router = express.Router();
var db = require('../db');

router.get('/', function(req, res, next) {
    db.query('SELECT * FROM usuarios', function (err, users) {
        if (err) {
            res.send(err);
        } else {
            res.render(
                'registro', {
                users: users
            });
        }
    });
});

router.post('/crearCuenta', function (req, res) {
    var user = {
        nombre: req.body.nombre,
        apelldo: req.body.apellido,
        email: req.body.email,
        password: req.body.password
    };

    db.query("INSERT INTO usuarios SET ?", user, function (err, result) {
        if (err) {
            res.send(err);
        } else {
            res.send(result);
        }
    });
}); 

module.exports = router;

my tabale "usuarios" is:

• id
• nombre
• apellido
• email
• password

When I try to create the user, I get:

{"code":"ER_BAD_FIELD_ERROR","errno":1054,"sqlState":"42S22","index":0}

I can't understand why is happening this.

Please help me
