How are you deploying your application? (if relevant)

Vercel

Describe the Bug

Combining i18n config option and edge runtime deployed on Vercel causes page render to fail. When I open index page it returns internal server error. Interestingly, when I add /index to the URL, page is rendering without error.

Failing URL: https://i18n-fail-repro.vercel.app
Working URL: https://i18n-fail-repro.vercel.app/index

I can't reproduce this issue on dev or prod builds. It happens only when deployed to Vercel.

I found a few issues that might be related: #42843, #42387.

Expected Behavior

When opening website index page should load without any errors.
