Next.js/Turbopack on Firebase Studio: Persistent "Unexpected token" parsing error, even after /clean command

Hi

I’m experiencing a persistent build error in my Next.js project hosted on Firebase Studio, which seems to be related to the build cache or the Turbopack parser.

Summary of the Problem: The build fails with a Parsing ecmascript source code failed: Unexpected token 'X'. Expected jsx identifier error whenever I try to render a new, moderately complex component. This happens even when the component’s code is syntactically correct and all dependencies are imported. The error persists even after running the /clean command multiple times.

Environment:

  • Platform: Google Firebase Studio
  • Framework: Next.js (App Router)
  • UI: shadcn/ui
  • Build Tool: Turbopack (default in this environment)

Steps to Reproduce:

  1. I have a working page component, for example, src/app/belbin-for-virksomheder/teamudvikling/page.tsx.
  2. I create a new, self-contained component (e.g., blockquote.tsx) and import it into my page.
  3. The build fails with the parsing error. The error message points to the first line of JSX after the <Head> component in my page file.

What I’ve Tried Without Success:

  • Running the /clean command in the Gemini chat multiple times.
  • Hard-reloading the browser preview (Ctrl+Shift+R).
  • Verifying all imports are correct.
  • Simplifying the component by removing dependencies like framer-motion and large data objects. The error still occurs.
  • Moving the new component’s code directly inside the page file (the “all-in-one” approach). The exact same error occurs, which strongly suggests it’s not an import/export issue.

My Hypothesis: This leads me to believe there is a persistent, un-clearable cache or a resource limit issue within the Firebase Studio build environment. The Turbopack parser seems to crash when processing the page with the new component’s complexity, resulting in a misleading syntax error.

My Question: Is there a more powerful way to completely invalidate and rebuild the entire project environment beyond the /clean command? It seems the build state is “stuck” and needs a hard reset.

Thank you for your help.
