Error message:

Turbopack Error: Failed to write app endpoint /page

Hey! 👋

This error usually appears when Turbopack can’t properly detect your Next.js version or when your build files are out of sync.

Turbopack Error: Failed to write app endpoint /page.
Turbopack version: v15.5.3-10-g26d61f1e9
Next.js version: 0.0.0

Why it happen ?

The next package might not be installed correctly (or corrupted in node_modules).

The package.json might show an invalid Next.js version (0.0.0 or missing entirely).

Cached build files in .next are mismatched with your current setup.

Fix Steps :

Install the correct Next.js version
Run this to ensure you have a valid version:

npm install next@latest react react-dom

Clean your environment
Remove old build and dependency files:

rm -rf .next node_modules
npm install

Check your package.json
Make sure it includes real version numbers (not 0.0.0):

"dependencies": {
"next": "15.0.3",
"react": "^18.3.1",
"react-dom": "^18.3.1"
}

Restart the dev server

npm run dev

Extra Tips

If you’re using a canary or experimental build, pin a stable version:

npm install [email protected]

Also, make sure your Node.js version is up to date (preferably ≥ v18).

You can read more in the official docs: Next.js Turbopack Documentation

Hope this helps!
This fixed the issue for me after cleaning the build and reinstalling next
