v0 project restore failure with SHA not available error despite GitHub commits

(edited)

Hi all — I’m looking for help/advice (or an official workaround) for a v0 project that got completely “nuked” by the very last generation, and I can’t restore any prior versions inside v0.

Problem

The most recent change set completely broke the app (nothing usable in the UI). When I try to restore earlier versions in the v0 UI, none of them work.

Error seen on restore:

Failed to sync PREVIEW to SHA <…>: SHA <…> is not available and could not be fetched from remote

Context

Project Connection: Connected to GitHub.
Workflow: No work was done outside v0 (no local commits, no force pushes on my side).
GitHub State: I can see commits/branches in GitHub (created by v0), but v0 can’t restore to specific SHA identifiers.
Incidents: I’m aware there has been an incident with elevated error rates — unsure if this is related.

What I’ve Tried

Restoring multiple versions in the v0 version dropdown — all fail.
Restoring older generations from chat history — also fails.

Questions

Is there any known workaround to restore a broken v0 project when the commit SHA isn’t fetchable?
Can v0 “lose” reachability to commits (e.g., force-push/rebase internally) so prior SHAs become unavailable?
What steps does the team recommend to recover a “last known good” state reliably?

If it helps, I can share screenshots or the exact SHA and branch naming pattern (I’m just not sure what’s safe to post publicly).

Thanks in advance — any pointers appreciated.

Hey, !

Sorry to hear you're experiencing this - I can definitely understand how frustrating it must be to have your project break like this, especially after investing so much time and money into building it.

Thanks for sharing all those detailed steps and context! That's really helpful for understanding what's happening.

To help the team investigate this issue, could you share your v0 chat link? It will look something like https://v0.dev/chat/... - this is essential for us to dig into what went wrong with the generation and the restore process.

Let us know how you get on!

Is this it?

How do I share the chat link?

Same problem here. Was editing a JSON content file directly in the file editor, working in preview mode. V0 was not pushing updates to the repo. Navigated away from the tab for a moment, came back, V0 reloaded, and I got hit with

**Failed to sync PREVIEW to SHA <…>: SHA <…> is not available and could not be fetched from remote**

And now I can’t load anything. Lost several hours of work (because again, V0 is not pushing to the remote on change of any files in the editor), and now I can’t load that branch at all in the chat to continue working. Pretty bad.

Thank you for sharing, folks! We hear you. We shipped some fixes yesterday, and working through some more today.

We also have been affected by several GitHub incidents which have caused a lot of these issues.

Is it possible to duplicate?
