How to Fix Not Found Error

Embedded apps currently rely on 3rd party cookies to authenticate. When the app runs, it sets a cookie in the browser. 

The app keeps track of the cookie and any other relevant information in a session on its server. The browser sends the cookie to the server with every request. For privacy reasons, browsers are now restricting the use of 3rd party cookies. This means that you can't use cookies to keep track of sessions of embedded apps. As an alternative to cookies, use session tokens to authenticate your embedded app. 

You can find more detail about it from Shopify Official Documentation
