Hi Vercel team,
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?
