“TypeError: Cannot read properties of undefined (reading ‘hasOwnProperty’)” error

EDIT: PROBLEM SOLVED.

I’m trying to make an update profile page for an Express app with Mongoose, and I got the error “TypeError: Cannot read properties of undefined (reading ‘hasOwnProperty’)”. I am confused how to fix it. Here is my code, thanks

exports.editProfilePost = async (req, res, next) => {
  try {
    const username = req.user.username;
    const user = await User.findOneAndUpdate({ username: username }, req.body, {
      new: true,
    });
    res.redirect('/profile');
  } catch (error) {
    next(error);
  }
};

So… idk why this works but I forgot to make the profile picture push to cloudinary. Somehow, not pushing to cloudinary made the req.body empty, resulting in the error.
