Inside cache, offline.html is always React's index.html

Question

I am caching an offline.html page. The cache is created properly and even an offline.html page is present inside the cache. Additionally, the build folder also has the right HTML file. However, the content of the offline.html is always React's index.html in both cache and source tab of the Chrome dev tools. Where is my mistake? Could this be an issue with serve?

Answer 1

Turns out serve -s build uses index.html for all not found requests because of the -s flag.
