Techs	Version
Next.js	15.5.2 (with turbopack)

Solution

Find your package.json file

Find the following lines:

   "scripts": {
     "dev": "next dev --turbopack",
     "build": "next build --turbopack",
     "start": "next start",
     "lint": "biome check",
     "format": "biome format --write"
   },

Remove the --turbopack from build command, so it becomes:

   "scripts": {
     "dev": "next dev --turbopack",
     "build": "next build", //LOOK HERE
     "start": "next start",
     "lint": "biome check",
     "format": "biome format --write"
   },

Notes

This error seems to affect Turbopack builds since removing --turbopack from the build script can resolve the build error. This error also mentioned here https://community.vercel.com/t/build-error-an-unexpected-error-happened-when-running-this-build/20836

Attempting to manually delete all the LICENSE and README files relating to hrana library from the Node Modules proven to not work for me. However, it may yields different result to other people as seen here https://github.com/vercel/next.js/issues/82881#issuecomment-3220603319
