User Profile Update fail - TypeError: user.then is not a function

[haganbt]

Any profile updates (press update profile button) fails with the below exception. This is true for "Profile Information" and "Change Password".

Stack: Node, Express, Bootstrap, no css or js frameworks, Mocha, MySQL

Node: v6.3.1

TypeError: user.then is not a function
    at exports.accountPut (/Users/ben/WebstormProjects/roadmeer/controllers/user.js:154:8)

Not too sure why we cannot call user.then as user appears return a promise. Interested to hear if anyone can advise.

As a workaround, I have simplified the control flow.

/**
 * PUT /account
 * Update profile information OR change password.
 */
exports.accountPut = function(req, res, next) {
  if ("password" in req.body) {
    req
      .assert("password", "Password must be at least 4 characters long")
      .len(4);
    req.assert("confirm", "Passwords must match").equals(req.body.password);
  } else {
    req.assert("email", "Email is not valid").isEmail();
    req.assert("email", "Email cannot be blank").notEmpty();
    req.sanitize("email").normalizeEmail({ remove_dots: false });
  }

  const errors = req.validationErrors();

  if (errors) {
    req.flash("error", errors);
    return res.redirect("/account");
  }

  let d = {
    email: req.body.email,
    name: req.body.name,
    gender: req.body.gender,
    location: req.body.location,
    website: req.body.website
  };

  if ("password" in req.body) {
    d = { password: req.body.password };
  }

  const user = new User({ id: req.user.id });

  user.save(d, { patch: true })
    .then(() => {
      if ("password" in req.body) {
        req.flash("success", { msg: "Your password has been changed." });
      } else {
        req.flash("success", {
          msg: "Your profile information has been updated."
        });
      }
      res.redirect("/account");
    })
    .catch(err => {
      if (err.code === "ER_DUP_ENTRY") {
        req.flash("error", {
          msg: "The email address you have entered is already associated with another account."
        });
      }
    });
};
