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. Berg (@berg-talentacommerce) · 2026-03-24 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. whosarmy-2256 (@whosarmy-2256) · 2026-03-25 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. whosarmy-2256 (@whosarmy-2256) · 2026-04-08 Coming back here to comment that these problems just got worse and worse in the past week. I spent a total of \~500 credits on the project and I believe a large chunk of these credits were wasted on issues like the one mentioned in this post. Of course, I’m guessing that the codebase getting larger contributed to the increased credit usage but still, lot of time wasted on the issues regardless. I submitted a couple of support tickets but didn’t hear anything back - overall quite disappointed as for a non-technical user (I’m not a developer) V0 initially felt like gaining super powers. On the plus side, this forced me to go right to the source of the super power and spend the time getting set up on Claude Code - it took a bit of time to figure out how to get set up but once it was done I’ve noticed that the friction is totally gone and it’s back to feeling like a super power again. I’m able to make quicker progress and running into less issues. I’ll be back on V0 again when it’s time to deploy through Vercel and hopefully some of the issues I was facing are resolved by then.
