I have a running application with Next 13 using the /app router.
I have a /not-found.tsx file inside my /app/[locale]/ that I want to use to customize my error page.

When I'm in [slug] and waiting for dynamic data, here is my functionnal code:

import { notFound } from "next/navigation";
...
  if (!work) {
    notFound();
  }

This code works, and return the not-found.tsx.
So, I have a /work page that contains all my works, and I have a /work/[slug] page for each works.

BUT, if I go to /workfdfdf manually, it render the default 404 This page could not be found. Next page.
I would expect my not-found.tsx file to be render? Following the official doc: https://nextjs.org/docs/app/api-reference/file-conventions/not-found.

Thanks!
