Hello Basir,

I was wondering if you already had a proposed solution to the error at 2 hours 20 minutes into the tutorial. It seems like they stopped supporting ReactDOM and maybe that’s the issue? I am not sure how to fix it myself because this is my first experience with web-based coding. I tried to post screenshots but I don’t have permission. The error occurred right after we put

<Nav className=”me-auto”>
                <Link to=”/cart” className=”nav-link”>
                  Cart
                  {createImageBitmap.cartItems.length > 0 && (
                    <Badge pill bg=”danger”>
                      {cart.cartItems.length}
                    </Badge>
                  )}
into the App.js file at the end of lesson 14 and checked the website for the cart counter. My website is just a white page now. Thank you for any help you can provide!

Here are the errors from the console:
