All builds FAIL on Metal builder "builder-ryvidd" — snapshot-target-unpack/main missing

Question

Hi Railway team,

All deployments for my service kairos-web (project efa8ffdf-96bf-4e76-a5a9-3541b675b810, service

06ab87ef-dd84-44d4-8df2-73b6bd6e849c) have FAILED since 2026-07-01 19:05:54 UTC-3 — that's 6 consecutive

failed deploys over ~24 hours.

The last successful deploy was 76aad374 on 2026-07-01 19:01:54 UTC-3. Production is still Online serving

traffic from that container.

Error pattern (consistent across all 6 failures):

[INFO] fetching snapshot

[INFO] unpacking archive

using build driver railpack-v0.30.0   (or nixpacks-v1.41.0)

Error: Failed to read app source directory

Caused by: No such file or directory (os error 2)

railpack/nixpacks exited with an error

scheduling build on Metal builder "builder-ryvidd"

Root cause appears to be Metal builder "builder-ryvidd" — the snapshot-target-unpack/main/ directory is never

created on the builder, regardless of build driver (railpack or nixpacks). Both fail reading from the same

missing path.

Things I've already tried:

- Multiple git push deploys (5 attempts) — same error
    - railway up (direct upload, bypasses git snapshot) — same error                                           
    - Switched builder from railpack to nixpacks via railway.toml [build] builder = "nixpacks" — same root

error, confirming it's the builder not the driver

- Verified Dockerfile is valid and builds locally                                                          
    - Verified production container is healthy (deploy 76aad374 from 07-01 still serving)

This is blocking all new deploys. Can you either:

1. Remove/repair builder-ryvidd from the pool, or                                                          
    2. Re-route my service to a different Metal builder, or                                                    
    3. Disable Metal builder for my service so it uses the legacy non-Metal builder?
