(node:39756) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:39756) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Here's my code

router.post("/login", async (req, res) => {

    try {

        const user = await User.findOne({ email: req.body.email });

        if (!user) {

            res.status(401).json("Something went wrong!");

        }

        const bytes = CryptoJS.AES.decrypt(user.password,

            process.env.SECRET_KEY);

        const originalPassword = bytes.toString(CryptoJS.enc.Utf8);



        if (originalPassword !== req.body.password) {

            res.status(401).json("Something went wrong!");

        }



        res.status(200).json(user);

    } catch (err) {

        res.status(500).json(err)

    }

});



module.exports = router;```
