Getting "Cannot find module 'next/headers' or its corresponding type declarations" error while trying to deploy to vercel. about next.js

https://github.com/mayank1513/nextjs-themes-ultralight/blob/24b3f05ede31c0444727af77cb6d73b829eb4f82/lib/nthul/package.json#L47-L56 looks like next is only added as an optional peer dependency. So it's likely not installed and such the import will fail.

You likely want to add it as a dev dependency for build to succeed.

(Note: the project did not use Turbopack, but Turborepo, which are different things. See https://turbo.build/)
