I probably have an issue with understanding how nextjs works in the "routing" regard. So my problem is i have a [...slug].js file within the pages routing system. In local dev i can get to that page and it works fine when i click through from the starting page of my application through a next/link <Link> ... however if i refresh that page using e.g. the browser refresh i just get unexpected token '<' errors for all the js files etc. What is going on here and what could be the issue ? I am using nextjs 14.
