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);
}
};
(error shown) [1]: https://i.stack.imgur.com/xss8j.png
The req.user could be undefined. To debug, add the checking:
let username = "";
if (typeof req.user !== "undefined") {
username = req.user.username;
}
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.
