### Verify canary release - [X] I verified that the issue exists in the latest Next.js canary release ### Provide environment information Operating System: Platform: linux Arch: x64 Version: #22 SMP Tue Jan 10 18:39:00 UTC 2023 Binaries: Node: 16.17.0 npm: 8.15.0 Yarn: 1.22.19 pnpm: 7.1.0 Relevant packages: next: 13.2.3 eslint-config-next: 13.2.1 react: 18.2.0 react-dom: 18.2.0 ### Which area(s) of Next.js are affected? (leave empty if unsure) App directory (appDir: true), Internationalization (i18n) ### Link to the code that reproduces this issue https://codesandbox.io/p/sandbox/next-13-2-i18n-static-params-error-3swobx ### To Reproduce 1. Create a page in `app/` directory with language routing and dynamic segment, e.g. `app/[lang]/blog/[slug]/page.tsx` 2. Add `generateStaticParams` with sample slugs and specifiec locale (e.g. `'en'`) 3. Add basic i18n config to `next.config.js`, defaultLocale and locales is enough. defaultLocale should have the same value as used in `generateStaticParams` 4. Run `next build` and observe error: ``` Error occurred prerendering page "/en/blog/test-1".
