v4 with NextJS v15.0.3 | ERROR: Package subpath './lib/util/toPath' is not defined by "exports

[therealgilles]

I'm trying out v4 beta and getting the following error with NextJs v15.0.3 in dev:

[28.11.2024 19:16.38.222] [ERROR]  ⨯ ./src/middleware.ts
Error: ./src/middleware.ts: Package subpath './lib/util/toPath' is not defined by "exports" in ./node_modules/tailwindcss/package.json
    at transformFile.next (<anonymous>)
    at run.next (<anonymous>)

Any clue or advice would be very much appreciated.

The automatic migration gives me the same error :/

For me, this occurred because a plugin I was using (tailwind-scrollbar) was incompatible with 4.0.0.

To discover this I commented out all the @plugin directives in my main tailwind file, then re-enabled them one-by-one.
