I built a React JS web app, which is working properly in my local network(i.e. localhost:3000), with npm start command. With the help of youtube tutorials, I deployed it on github pages, the optimized build version of the app (created with npm run build) is not working at all. The Album track and artist names are visible, but album cover photo and mp3 audio is not populated. The GitHub page is published on: https://afridi-haque7.github.io/melophile/

There you can see the source code also.

The expected webpage screenshot is pasted below:
