Hey guys I am building a fullstack website to to learn Express , Sequelize and REST api

I have this model for a post request “

module.exports = (sequelize, DataTypes) => {
  const PaymentMethods = sequelize.define("payment_methods", {
    email: {
      type: DataTypes.STRING,
      allowNull: false,
    },
    cardnumber: {
      type: DataTypes.STRING,
      allowNull: false,
    },
    expirydate: {
      type: DataTypes.DATE,
      allowNull: false,
    },
    CVC: {
      type: DataTypes.STRING,
      allowNull: false,
    },
  }, {
    timestamps: false
  });

  return PaymentMethods;
};

Then we use it in this file

const express = require('express');
const router = express.Router();
const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY);
const db = require('../models');

router.post('/payment/updatepaymentmethod', async (req, res) => {
  try {
    const { email, cardNumber, expDate, cvc } = req.body;

    // Create a new payment method record in the database
    const newPaymentMethod = await db.PaymentMethods.create({
      email: email,
      cardnumber: cardNumber,
      expirydate: expDate,
      CVC: cvc
    });

    // Return success response
    res.status(200).json({
      success: true,
      message: 'Payment method updated successfully',
      paymentMethod: newPaymentMethod
    });
  } catch (error) {
    console.error('Error during payment method update:', error);

    // Log the error object for debugging
    console.log(error);

    res.status(500).json({
      success: false,
      message: 'Payment method update failed',
      error: error.message
    });
  }
});

module.exports = router;

I get this error

"error": "Cannot read properties of undefined (reading 'create')"

If I change the method to update it still does so.

And the weirdest thing is that I have another request on a different model but with exactly the same structure and it works perfectly fine.

I tried several things to fix it but none of them worked or I ran into stuff I don’t really know, like changing the index.js file properties From what I understood the problem is the model importing into my file.

It should allow me to push some data to my database table payment_methods
