Query in Sequelize getProducts method - node.js

Question

I am implementing an E-Commerce site in NodeJS. I am using Sequelize for managing MySQL.
But I am getting an error while using getProducts() method.
The code of the function where I am using the getProducts() mehtod is as below
exports.postCart = (req, res, next) => {
const p_id = req.body.p_id;
// console.log(p_id);
let fetchedCart;
let newQuantity = 1;
req.user
.getCart()
.then((cart) => {
fetchedCart = cart;
console.log(p_id);
return cart.getProducts({ where: { id: p_id } });
})
.then((products) => {
let product;
if (products.length > 0) {
product = products[0];
}
if (product) {
// ....
}
return Product.findByPk(p_id)
})
.then((product) => {
return fetchedCart.addProduct(product, {
through: { quantity: newQuantity }
});
})
.then(() => {
res.redirect("/cart");
})
.catch((err) => {
console.log(err);
});
};
I am following a tutorial which I think is using an older version of sequelize. I am using 6.3.0 version of sequelize. So is the method getProducts() not available in sequelize 6 or an I am typing something wrong.
Any help is welcomed :D
Thanks in advance :)
