Error at Query.run, might be located at auth.js

I am currently trying to redo your project on my own without heroku, hosted on localhost. Whenever I use postman to test the endpoints, I keep getting this error on my console:

Server started at http://localhost:5000

This is my current code for auth.js:

const { Op } = require("sequelize");
const { User } = require('../sequelize');
const bcrypt = require("bcryptjs");
const jwt = require("jsonwebtoken");
const asyncHandler = require('../middlewares/asyncHandler');

// exports.signup = asyncHandler(async (req, res, next) => {
//  console.log('this function works');
// });

exports.signup =  asyncHandler(async (req, res, next) => {
    const user = await User.create(req.body);

    await user.save();

    res.status(200).json({ success: true, data: token });

    console.log('this function works');
    
}); 

Did you ever experience something like this before?
