got it this way

const authenticateUser = async (connection,  req, res) => {

  const user = await User.findUser(connection, req.body.username)
    if(!user){
        return res.render('login/login',{error: true})
    }
    if(!await bcrypt.compare(req.body.password, user.password)){
        return res.render('login/login', {error: true})
}
    else{
      if(user.user_type_id==1){
        req.session.user = user
        res.locals.user = user
      res.redirect('/Administration/index');
    }else if(user.user_type_id==2){
      req.session.user = user
      res.locals.user = user
      res.redirect('/Administration/index');
    }else if(user.user_type_id==3){
      req.session.user = user
      res.locals.user = user
      res.redirect('/Administration/index');
    }else if(user.user_type_id==4){
      req.session.user = user
      res.locals.user = user
      res.redirect('/Administration/index');
      }
      else if(user.user_type_id==5){
        req.session.user = user
        res.locals.user = user
        res.redirect('/Administration/index');
    } else {
        console.log("banned");
    }



  }
}
