Since approximately 2025-11-25 05:30 UTC, all new deployments are failing with the error "Failed to build an image". No detailed build logs are provided - only the following appears:
[inf] scheduling build on Metal builder "builder-zdnszj"
[inf] fetched snapshot sha256:... (12 MB bytes)
[inf] [snapshot] fetching snapshot, complete 12 MB
Then the build immediately fails without any error details.
What I've tried:
Rollback to last successful deployment - Works fine (commit 2594746)
Deploy using
railway upfrom apps/server directory - FailsDeploy identical code that was previously successful - Fails
Removed new files (.sql migration file) - Still fails
Reverted all code changes to last working commit - Still fails when using
railway up
Environment:
Railway CLI version: 4.11.1
Builder: Nixpacks (nixpacks.toml)
Node version: 18
Root directory: apps/server (monorepo structure)
Recent failed deployment IDs:
cc9d567f-91ea-48b4-a231-24ae9b4dee41
019d60cb-35e4-4208-afcf-36a3208cabbd

Last successful deployment:
Commit: 259474633104cb314b1c75928d3774088775645b
Time: ~2025-11-25 05:29 UTC
Questions:
Why are there no detailed build logs showing the actual error?
Is there an issue with the Metal builder "builder-zdnszj"?
Why does rollback work but new deployments fail, even with identical code?
Please investigate and provide detailed error logs.
Thank you.

Found the issue!
The build was failing because "Use Metal Build Environment" was enabled in Railway settings. Turning it off fixed the problem - builds are working normally now.
