not-found.jsx file in app/[lang] ignored for non-existent inner folders (with Internationalization) about next.js HOT 3 OPEN

i think not-found pages are only shown when the notFound() function is thrown. see next.js docs.

to display the nested [locale]/not-found page, you can add a catch-all route segment at [locale]/[...404]/page.tsx which calls notFound(). this is what e.g. next-intl recommends - see their docs for an example.

The linked doc also say it catches all the unmatched urls with this not-found.jsx;

And it does that well in our project without the [lang] folder. Only when we add the [lang] folder does this issue happen.

Will try out this catch-all route segment approach but this issue needs to be resolved on the root cause itself.
