Response headers blocked with addprefix?

Traefik Traefik v2

I'm running ubooquity in a swarm, and when trying to use the AddPrefix, it does not seem to work.

What I am expecting:
type in ebook.home and get directed to the /ubooquity/admin prefix I have added in my rules.

What I am getting:
I get a the login page, but its not rendered(?) properly. There are errors in the browser console saying that The stylesheet https://ebook.home/ubooquity/admin-res/angular-material.min.css was not loaded because its MIME type, “text/html”, is not “text/css”

If I remove the add prefix rule, and manually type the path it, everything works, ebook.home/ubooquity/admin the page loads correctly. So I'm not sure where things are going wrong.

When the page does load, I notice content type of the response header is application/javascript, is there something special to make this work through a reverse proxy?

Also, I knew nothing about docker or web dev 5 days ago, so my terminology might be a little lacking. Thanks!
