v0 Turbopack caching stale syntax errors after file rewrites

Problem

I’ve been burning a lot of credits while hitting the same issue over an over regarding stale cache entries.

When a file is edited that contains a syntax error (e.g. an unclosed template literal), Turbopack correctly flags it. After the file is fixed — including full rewrites via the v0 Write tool producing a syntactically valid file — Turbopack continues to report the original error from the broken version, even though the file on disk is now correct.

The error persists across:

  • Single-line edits to the fixed file
  • Comment additions to force a re-parse
  • Full file rewrites (Write tool replacing the entire file contents)

The only observable behaviour is a blank preview pane with the stale error displayed in the diagnostics panel. The error resolves eventually (seemingly on its own) but not predictably, burning time and credits while we retry edits trying to “fix” a problem that is already fixed.

Steps to Reproduce

  1. Edit an API route to introduce a syntax error (e.g. an unclosed backtick in a template literal)
  2. Observe correct error in Turbopack
  3. Fix the file completely (full rewrite)
  4. Turbopack continues reporting the original error for multiple subsequent builds
  5. Adding trivial edits (comments, whitespace) to force re-parse does not resolve it

Expected Behavior

After a file is rewritten with valid syntax, Turbopack should clear the error on the next build.

Impact

Burning credits while distinguishing between “file is still broken” and “Turbopack has a stale cache entry”, leading to repeated unnecessary edits.

I am also seeing these errors now. Builds are failing and there is no more “fix free” button. I don’t appreciate having to pay to fix this kind of stuff.

Creating rules in md to ignore these errors has provided some temporary relief. The caching issue seems to fix itself after about 5 mins and a hard refresh. But yes, I would estimate I also burned through about 30 credits over the course of a couple days before I found this workaround.

I’m not sure what’s happened but V0 used to feel effortless and the “fix free” was a nice touch but something has shifted in the last couple weeks.
