Build fails before start: Resource provisioning failed (Neon)

Hi,

I’m hitting a blocking issue with Resource Provisioning that makes the project completely undeployable.

The deployment fails before the build starts, logs never load, and the process always stops at:

Provisioning Integrations
Neon: Create database branch for deployment

This is the exact same issue described here:
https://community.vercel.com/t/build-failed-resource-provisioning-failed-build-logs-not-loading/21495

Timeline / what happened before it broke

Initially, deployments were working almost fine:

  1. The build actually started and progressed normally.
  2. It then failed during the build due to:
  • an outdated Next.js version
  • reported vulnerabilities / security warnings.

At this stage:

  • provisioning completed successfully,
  • build logs were available,
  • the failure was a standard build failure (not related to provisioning).

Next:

  1. Vercel automatically created a GitHub branch suggesting an update to the Next.js version.
  2. I merged that GitHub branch into my main branch after updating Next.js and fixing the reported issues.

After this merge:

  1. Deployments stopped working entirely.
  2. The build never starts.
  3. Build logs are no longer available.
  4. Every deployment now fails at Resource Provisioning, before the build phase.

At this point, the project appears to be stuck in a broken provisioning state.

The project is effectively bricked due to a stuck provisioning state.
