I am new to working with Postman, and I am working on learning the MERN tech stack, starting with this tutorial playlist (MERN Authentication System With Email Verification). I am on this video (Storing User With Hashed Password), and from what I can tell, my overall code is fine, but I may have a simple mistake somewhere. I have looked over other solutions for this problem, but none of them have helped. I have attached my code below.

Model

const mongoose = require("mongoose");
const bcrypt = require("bcrypt");
    
const userSchema = new mongoose.Schema({
    name: {
        type: String,
        required: true,
    },
    email: {
        type: String,
        unique: true,
        required: false,
    },
    password: {
        type: String,
        unique: true,
        required: false,
    },
});
    
userSchema.pre("save", async function (next) {
    if (this.isModified("password")) {
        const hash = await bcrypt.hash(this.password, 8);
        this.password = hash;
    }
    next();
});
    
module.exports = mongoose.model("User", userSchema);

Controller / Create User Function

const User = require("../model/user");
   
exports.createUser = async (req, res) => {
    const { name, email, password } = req.body;
    const user = await User.findOne({ email });

    if (user) {
        return res
            .status(400)
            .json({ success: false, error: "This email is already registered" });
    }
    
    const newUser = new User({
        name,
        email,
        password,
    });
    
    await newUser.save();
    return res.send(newUser);
};

Validator Middleware

const { check, validationResult } = require("express-validator");
    
exports.validateUser = [
    check("name")
        .trim()
        .not()
        .isEmpty()
        .withMessage("Name is required.")
        .isLength({ max: 20 })
        .withMessage("Name cannot be more than 20 characters."),

    check("email").normalizeEmail().isEmail().withMessage("Invalid Email"),
    
    check("password")
        .trim()
        .not()
        .isEmpty()
        .withMessage("Password is required.")
        .isLength({ min: 8, max: 20 })
        .withMessage("Minimum of 8 characters; Maximum of 20 characters"),
];
   
exports.validate = (req, res, next) => {
    const error = validationResult(req).array();
    if (!error.length) return next();
  
    return res.status(400).json({ success: false, error: error[0].msg });
};

Here are the images of the smaller files:

• App.js
• Database Connection
• Create User Route

This is my result in Postman:
Result from Postman

It should be noted that [email protected] is not already saved in the database.

Finally, I am aware that I have an issue with semicolon consistency, and I am working on it. The same goes for making my code look cleaner.

Thank you for your help!

Edit: Woke up, and it worked. No changes to the code was made.
