This deployment failed at the container creation stage due to a platform-level issue. The build, image publish, and pre-deploy command all completed successfully, and the same configuration worked on May 8. Multiple consecutive deployments have failed with the same error since May 9, so try redeploying or contact support if the problem persists.

I'd fix the UndefinedVar error, but not sure if this is breaking your deployment/build...?
Also, I'd recommend switching to Dockerfile or Railpack as Nixpacks is deprecated.

I would reccomend to switch to a dockerfile and then post the error again if it happens and maybe the dockerfile aswell.
