OR clause in where condition not working

[sgda021992]

Hi,

I have a query like (Select * from users where user.name='asd' OR user.lastname = 'asdaff')

I have written my code like this:-

Users.findOne(
{
where: {
or: [
{ name: req.params.name },
{ lastname: req.params.lastname }
]
}
}, function (err, user) {
if(user) {
done(user, null);
} else {
done(null, err);
}
});

but it's not working throwing me error null.
Can u tell me how can i achieve this.
