My v0 project preview has stopped loading. The preview pane shows “Failed to load preview” and, on retry, the error:
Could not get credentials from OIDC context. Please make sure OIDC is set up for your project — Docs: https://vercel.com/docs/oidc
What I’ve already verified/tried:
The dev server itself is healthy — it’s running (Next.js 16.2.0) on port 3000 and returns HTTP 200 with the full rendered page when requested directly.
My application code does not call the AI Gateway, Vercel SDK, or any AWS/OIDC-dependent service at request time, so the OIDC credential request appears to be coming from the platform/sandbox layer, not my app.
Clicked Retry in the preview multiple times — no change.
Did a hard restart of the preview and a full editor tab reload — no change.
Manually restarted the dev server — it boots cleanly and serves a 200, but the preview iframe still cannot connect.
This looks like the sandbox’s short-lived VERCEL_OIDC_TOKEN is expired or not being re-provisioned for the preview proxy. Could you please re-provision/refresh the OIDC credentials for this project’s sandbox?
Same error here… I tried to apply changes many times but nothing was happening.
I aslo tried to edit the code manually but coudl’nt save it.
Few min ago, I got a message informining that I didn’t have credits anymore..?
and total credits isn’t displayed in the corner anymore, and I get an error in billing settings…
