NextJS custom 404 page is not showing up

Question

I have the 404.tsx file in the apps/specificapp/pages/ directory, but NextJS still displays the default pre-generated 404 page.

Am I misunderstanding the documentation, or is something preventing me to override the default 404 page?

Answer 1

So as it turns out the next.config.js configured to project to only accept the file extensions page.tsx, page.ts, page.jsx and page.js. I changed my filename to 404.page.tsx and it's working perfectly now.
