Insert function in node in postgre

Hello i am following a tutorial and trying to do a simple insert query but getting 404 error.

function

function insertUser(req, res, next){
  req.body.users = parseInt(req.body.users);
  
  db.none('INSERT INTO office.users VALUES (role_id,office_id,user_name,full_name)'+
           'values(${role_id},${office_id},${user_name},${full_name})', req.body.users)

   .then(function(){
        res.status(200)
        .json({
          status: 'success',
          message: 'Inserted one user'
   });
   })
 .catch(error => {
        console.log(error);
        next();
})
}

The stack trace says problem is near "values".i am not getting it.following i flow with the documentation.Something wrong with the query?

Stack trace
