> Export encountered errors on following paths:
    /_not-found

• I don't have any _not-found files in my project.
• I have no static pages in my project as well, the problem comes from /_not-found file.
• I was trying to create not-found.tsx file in [locale] directory, it does not help.

To Reproduce pnpm build

Expected behavior It should build without any errors.

About (please complete the following information):

• next-international version: 1.1.3
• Next.js version: 13.5.6

Can you share a minimal reproduction? Looking at the error, it seems like you're never calling setStaticParamsLocale: https://next-international.vercel.app/docs/app-static-rendering#static-rendering
