How to update req.user session object set by passportjs?

Question

I\'m trying to do this since a lot of days but all my tests fails...

Users on my platform connect them by using passportjs strategies (paypal, facebook, google...).<

Quan Duong's answer was the most useful to me, but here is a bit more realistic scenario:

async function foo(req, res) {
  // get some data from somewhere
  const newNickname = req.body.nickname;

  // update the user database somehow - e.g. mongodb 
  const users = db.getCollection('users');
  await users.updateOne({
    _id: req.user._id
  }, {
    $set: {
      nickname: newNickname
    }
  });

  // create a temporary copy of the user w/ the updated property
  const updatedUser = req.user;
  updatedUser.nickname = newNickname

  // persist the change to the session
  req.login(updatedUser, async(error) => {
    if (error) {
      res.json({
        err: 'Sorry, there was an error updating your account.'
      });
      return;
    }

    /* 
       maybe you need to call another function from here that uses the updated info before 
       responding to the original request
    */
    try {
      await bar(req.user);
    } catch (error) {
      res.json({
        err: 'Sorry, there was an error updating your account.'
      });
      return;
    }

    // done
    res.send(200);
  });
}
