This is a change introduced in recent release. You can find it here in detail https://medium.com/passportjs/fixing-session-fixation-b2b68619c51d

From the documentation https://www.passportjs.org/concepts/authentication/logout/

try below code

router.get("/logout", function(req, res, next) {
  req.logout(function(err) {
    if (err) {
      return next(err);
    }
    res.redirect("/");
  });
});
