Use async keyword before anonymous callback (err, user) function.

jwt.verify(token, process.env.ACCESS_TOKEN_SECRET, async (err, user) => {
  // your code...
  const refrsh = await User.findOne({
    where: {id:req.body.kakaoid}
  });
 // your code...
});

You need to add async when decalre function that you want await:

 jwt.verify(token, process.env.ACCESS_TOKEN_SECRET, async (err, user) => { ...

Simply make the (err, user) callback an async function. It should work out alright in this particular case:

exports.authenticateToken = (req, res, next) => {
  const authHeader = req.headers["authorization"];
  const token = authHeader && authHeader.split(" ")[1];
  if (token == null) return res.sendStatus(401);
  jwt.verify(token, process.env.ACCESS_TOKEN_SECRET, async (err, user) => {
    if (err) {
      const refreshToken = req.body.refreshToken;
      const refrsh = await User.findOne({
        where: { id: req.body.kakaoid },
      });
    }

    req.user = user;
    next();
  });
};
