Pages with rewrite failing to load #2

[thiras]

The previous issue (#1031) has been closed because of the wrong reproducible example. But it's fixed and the example repository reproduces the bug consistently now.

Describe the bug

The pages with translation failed to load (500) if they have rewritten to a destination. This problem only occurs against a direct hit to the rewritten URL. Client-side navigation works totally fine.

Occurs in next-i18next version

8.1.0

Steps to reproduce

I've created a reproducible repo here; https://github.com/thiras/next-i18next-rewrite-bug Just deploy it on Vercel and hit /tr/hakkimizda directly (Turkish equivalent of /about)

Expected behaviour

Translations should work with the rewrites. Rewrites are the best option to handle slug translation so far.

Screenshots

Here is the vercel error output;

You will need to use path.resolve to instruct the Vercel platform to keep your public/locales dir. Here is a relevant comment. Good luck!

Omg finally. I was going to mad while trying to figure out the problem. Thank you very much.
