Error message:

Turbopack Error: Failed to write app endpoint /dashboard/page

This looks like an internal issue with Turbopack (Next.js's underlying engine) when compiling the App Router's structure, often related to CSS or file resolution.

Possible fixes

• Delete Cache and Reinstall: This is the most common fix for cryptic Turbopack errors.
• Restart the dev server (npm run dev --turbo).
• Check globals.css (or CSS Imports): Many similar "Failed to write app endpoint" errors trace back to an issue compiling the main CSS file.
• Remove --turbo: Since this is a known unstable feature, running without Turbopack may be necessary.
• Check File Paths (Monorepo): If you are using a monorepo (e.g., Turborepo, pnpm workspaces), the issue could be Turbopack's difficulty resolving symlinked paths.
• Upgrade to Canary: If the error persists, update Next.js to the absolute latest canary version to see if a recent Turbopack fix resolves it.
