Ionic elements not showing on built version of app

Ionic Framework Ionic Angular
1

Hello!

I am working on a small personal project and have run into a bit of an issue. When I build my app and host it locally with http-server none of the Ionic components show, although they are present in my browsers DOM with a 0px height. What makes it confusing to me is that when I had been testing using Ionic serve everything had been showing up as expected and there were no errors present in the developer console.

Going off other forum posts it seems like the issue might be in the angular.json file so I have attached that below

Any pointers on where this issue could be coming from would be appreciated
