NEXTJS Dynamic routes return 404 no matter what

Question

I'm trying to reach http://localhost:3000/nba/category-slug-3 but I keep getting 404 error. http://localhost:3000/nba works fine but any slug does not work. Am I missing something? Do I need to add/edit another file? I just started using NextJS. At some point I want to be able to use item id's from a mongodb collection as the slug.

It looks like you named your page [slug.js] when you may have meant to name it [slug].js.
