Hi,

unfortunately this only works if the middleware is not at the root e.g. test/_middleware.ts.
If I try this with the middleware at the root I get this error (12.0.8-canary.18):

> Build error occurred
TypeError: Cannot destructure property 'files' of 'middlewareManifest.middleware[page.replace(...)]' as it is undefined.

Fixes [a small bug](#32967 (comment)) that caused the build to crash if a _middleware is present at the root of the project and standalone mode is enabled.
