Hey there!

I belong to an open source security research community, and a member (@ktg9) has found an issue, but doesn’t know the best way to disclose it.

If not a hassle, might you kindly add a SECURITY.md file with an email, or another contact method? GitHub recommends this best practice to ensure security issues are responsibly disclosed, and it would serve as a simple instruction for security researchers in the future.

Thank you for your consideration, and I look forward to hearing from you!

I was expecting that in backend (or at least in frontend) there would be a check if the order is belonging to user (or seller or admin).
It seems that anyone could access to orders of another user (thus also some additional data such as shipping address).

How to fix this issue? can you teach me how to fix this issue?

i am facing this issue in cartScreen.js-

Uncaught TypeError: cartItems.map is not a function
can anyone help?

TypeError: Cannot read property 'map' of undefined

getting this error while working on "Create React App" assignment. The error is coming from App.js

Hello, I finished the course and pressing 'F12' to be responsive, the header is broken. I downloaded the "amazona master" from your repository and it also contains such an error. I hope someone can help me, I will be grateful.

By copying unavailable item id to cart with qty link for example https://amazona.webacademy.pro/cart/5f7ae598281b5e7551d188bb?qty=1
It will add and let you proceed to the payment screen.

Unhandled Rejection (TypeError): Cannot read property 'product' of null
(anonymous function)
In video-15 I got this error

Help me to solve this

Products are not showing on Home Screen after connecting to MongoDB (edits to server.js) and deleting ID from products in backend data.js

Hllo please help me when I deploy it to heroku and when I will connect with MongoDB atlas it will not insert my sample users and product into online MongoDB atlas database so i will copy paste products data manually it will show product but when I click on product It will show error product not found can you help me to solve this.
And when I register as newbuddy it insert data in online database and also signin works with that .

The Continue button on Payment Method Screen (PayPal/Stripe) is not working or redirecting to Place Order Screen.

If you are stuck in this part maybe you need to delete mongodb database and recreate it, that solved my problem.

I downloaded your full repository and have this error too..
Thanks

Good Afternoon Basir,

Thank you for the tutorial. When I move .gitignore from src to root, I get the terminal error: "nothing added to commit but untracked files present."

I can not see the map screen. instead loading box is ocuuring infinite. i done everthing according

.

Hi. There's a problem with error handling. Whenever you enter a wrong product id in the browser bar, the response must be 404 Product Not Found. But, if you enter manually an ID that is not in MongoDB format (for example, if you make it shorter) the backhand throws an error in 'find' function which is shown on the front end. How can we check for correct formatting? Preferably before the request goes, so that we could redirect the user immediately.

The state of cart (if there were items in it) is not set to empty when user signs out.

export const signout = () => (dispatch) => {
localStorage.removeItem('userInfo');
localStorage.removeItem('cartItems');
dispatch({ type: USER_SIGNOUT });
};

import React, { useEffect, } from 'react';

import Product from '../components/Product';
import LoadingBox from '../components/LoadingBox';
import MessageBox from '../components/MessageBox';
import { useDispatch, useSelector } from 'react-redux';
import { listProducts } from '../actions/productAction';

export default function HomeScreen() {
const dispatch = useDispatch();
const productList = useSelector((state) => state.productList);
const { loading, error, products } = productList;

useEffect(() => {
dispatch(listProducts());
}, [dispatch]);
return (

I'm getting a : TypeError: Cannot read property 'category' of undefined

Can anyone help

?

Hello Basir, thank you for providing this as a reference and making this code available. I went through some of the tutorials on YouTube and thought I would try to fork and start fresh from your repo. I was having an issue with running the seed URL on localhost.
from: " 5. Seed Users and Products
Run this on chrome: http://localhost:5000/api/users
It returns admin email and password ";

{
"message": "ENOENT: no such file or directory, stat '/Users/johnsasser/Desktop/SandBox/amazona/frontend/build/index.html'"
}

is the return message from the req.
I got 500 internal server err on the GET req.
I received the same results from both seeding instructions. Is there something simple I am missing?

facing these issues at the homeScreen.js

`import React, { useEffect, useState } from 'react';
import axios from 'axios';
import Product from '../components/Product';
import LoadingBox from '../components/LoadingBox';
import MessageBox from '../components/MessageBox';

export default function HomeScreen() {
const [products, setProducts] = useState([]);
const [loading, setLoading] = useState(false);
const [error, setError] = useState(false);
useEffect(() => {
const fecthData = async () => {
try {
setLoading(true);
const { data } = await axios.get('/api/products');
setLoading(false);
setProducts(data);
} catch (err) {
setError(err.message);
setLoading(false);
}
};
fecthData();
}, []);

Hi,

I keep getting "SyntaxError: Unexpected identifier" when trying to run node in the beginning of lesson 9.

I also added "type": "module" in the package.json. Nothing works.

Here is my code in server.js:

`import express from 'express';
import data from './data.js';

const app = express();

app.get('/api/products', (req, res) => {
res.send(data.products);
});

app.get('/', (req, res) => {
res.send('Server is ready');
});

app.listen(5000, () => {
console.log('Serve at http://localhost:5000');
});`

Hi,
do you have any solution for flickering UI while loading?
Thanks.
