Resolved: Cant access username before Intialization when I try to use an async function to call a promise

async function user(req, res) {
  let key = req.cookies['cookie']
  return new Promise((resolve, reject) => {
    connection.query('SELECT * FROM accounts WHERE `key` = ?', [key], (error, results, fields) => {
      if (error) {
        return console.log(error)
      }
      if (results.length > 0) {
        resolve(results[0].username)
      }
    });
  }
  )
}

async function grabinfo(req, res) {
  res.render('dashboard', { title:'Dashboard', username: username});
  const username = await user(req, res)
}


module.exports.grabinfo = grabinfo
