@riley-pearce-airteam this is not specific to Payload, this happens in a new blank NextJS project after adding middleware.

You can test this out by running pnpm create-next-app@rc --empty and then adding your middleware file the src directory. Be sure to remove .next folder before re-building to see the results.

Good catch @JarrodMFlesch, thanks for that. I will take a look over at the Next.js issues and see if the issue has been raised before.
