github pages + namecheap domain = response status 404

Question

I'm trying to add a domain name to my react app but I get a 404 response when I added it. It works fine in github pages hosting but when I add the domain I get the error. not sure if I'm missing something in my package.json file? please help, I've been stuck for quite some time now.

this is my package.json

Your website is trying to fetch the static assets (JS and CSS) from the wrong URL. It's requesting them at https://www.casahogarscj.com/casaHogar/static/... while Github serves them at https://www.casahogarscj.com/static/... (without casaHogar).

To fix this, you need to change the homepage value to https://www.casahogarscj.com/ in your package.json and rebuild your website.
