I know this question has been asked a lot of times but the majority of them is for frameworks or other tech stacks, I'm using NodeJS with Express and a database on MongoDB and I'm testing my API with Postman. When I try to send the request to the API on POST return the next message (ON the app, Postman just sends: Could not get response):
addProductsCart.js:21 _req$body = req.body, name = _req$body.name, description = _req$body.description, image = _req$body.image, price = _req$body.price, productType = _req$body.productType; ^ TypeError: Cannot read properties of undefined (reading 'name')
going to the file that the error sends it seems like there's nothing wrong
import Product from '../models/Products';
import Cart from '../models/Cart';
const addProductCart = async (req, res) => {
const {name, description, image, price, productType} = req.body;
const estaEnProducts = await Product.findOne({name});
const noEstaVacio = name !== "" && description !== "" && image !== "" && price !== "" && productType !== "";
const estaEnElCarrito = await Cart.findOne({name});
if (!estaEnProducts) {
res.status(400).json({
mensaje: "This products is not in our DataBase",
});
} else if (noEstaVacio && !estaEnElCarrito) {
const newProductInCart = new Cart({name, description, image, price, productType, amount: 1 });
/* Update the property of inCart */
await Product.findByIdAndUpdate(
estaEnProducts?._id,
{ inCart: true, name, description, image, price, productType },
{ new: true }
)
.then((product) => {
newProductInCart.save();
res.json({
mensaje: `Product added correctly`,
product,
});
})
.catch((error) => console.error(error));
/* Validate if product is already in cart */
} else if (estaEnElCarrito) {
res.status(400).json({
mensaje: "Product already in cart",
});
}
};
module.exports = addProductCart;
in my models i'm using the exact same names for the controllers:
import {Schema, model} from 'mongoose';
const cartSchema = new Schema({
name: {type: String, required: true, unique: true},
description: {type: String, required: true},
image: {type: String, required: true, unique: true},
price: {type: Number, required: true},
productType: {type: String, required: false},
amount: {type: Number, required: true},
});
export default model('Cart',cartSchema);
and this is the product model:
import {Schema, model} from 'mongoose';
const productsSchema = new Schema({
name: {type: String, required: true, unique: true},
description: {type: String, required: true},
image: {type: String, required: true, unique: true},
inCart: {type: Boolean, default: false},
price: {type: Number, required: true},
productType: {type: String, required: false},
});
export default model('Products',productsSchema);
I'm using Import instead of require with Babel so there's no problem there
I'm not able to found the error there, also I think I'm doing the petition correclty on Postman (Using the next JSON, that is a product created before on DB and telling Postman on headers that the Content-type is application/json)
{
"name": "producto-test",
"description": "descripcion de prueba",
"image": "https://cdn.betterttv.net/emote/58ae8407ff7b7276f8e594f2/3x",
"price": 100000,
"productType": "Camara"
}
If someone knows what I'm doing wrong I'll really apreciate that, finally I let all the log of the error, if may be helpful

req.body is undefined. Did you add json() to your express app? If not add it
const app = express()
