NODE_ACL should generate error status 403

I am using node_acl, it is working fine but whenever any request get denied it generates 500 Internal Server Error but it should show 403 Access denied error.

I am using Express js (version 4.13.4), so in app.js file I changed the code :

app.use(function(err, req, res, next) {
    res.status(err.errorCode || err.status || 500);
    res.render('error', {
        message: err.message,
        error: {}
    });
});

to

app.use(function(err, req, res, next) {
    res.status(err.errorCode || err.status || 500).send({status:'fail', data:err.message});
});

Now it works perfectly.
