Hi Railway Support,

I'm experiencing a critical deployment issue with my backend service where builds are

failing consistently.

Symptoms:

- Railpack successfully prepares the build plan

- Build logs show "Successfully prepared Railpack plan for build"

- But then the actual build commands (npm ci, build step) never execute - zero output

- No error messages, just silent failure after plan preparation

Timeline:

- Last successful deployment: March 14, 2026 ~2:00 AM UTC (commit cfc577d)

- Issue started: All deployments after this commit fail with the same pattern

- Every deployment since then (10+ attempts) shows the same behavior

What I've tried:

- Clearing Root Directory field (blank vs / vs /backend)

- Removing/modifying Build Command

- Deleting and restoring Dockerfile

- Regenerating package-lock.json

- Manual deploys vs auto-deploys

- All produce the same result: plan prepares, then nothing executes

Project details:

- npm workspaces monorepo structure (backend, frontend, shared packages)

- Node.js 20.20.1

- Railpack 0.18.0

- No billing issues, no resource warnings visible in dashboard

Example failed deployment logs:

[inf] ╭─────────────────╮

[inf] │ Railpack 0.18.0 │

[inf] ╰─────────────────╯

[inf] ↳ Detected Node

[inf] ↳ Using npm package manager

[inf] ↳ Found workspace with 2 packages

[inf] Steps

[inf] ──────────

[inf] ▸ install

[inf] $ npm ci

[inf] ▸ build

[inf] $ cd backend && npm install && npx playwright install --with-deps chromium &&

npm run build

[inf]

[inf] Successfully prepared Railpack plan for build

[inf]

[inf]

(deployment fails here - no further output)

Is there a known issue with Railpack execution, or has something changed with the

platform? The fact that the exact same commit worked yesterday but nothing works now

suggests a platform-level issue.

Can you help investigate what's blocking the build execution?

Thank you!
