Hey Railway team

I have a front-end-only Next.js 14 app deployed to Railway. The deployment completes successfully, but shortly after, it crashes repeatedly with the following error:

Error: "next start" does not work with "output: export" configuration. Use "npx serve@latest out" instead.

Context:

• App is static only (no backend)

• output: 'export' is set in next.config.js

• Using next@14.2.30

• Docker-based deployment on Railway

• Current start script: "start": "next start -p $PORT"

Logs:

▲ Next.js 14.2.30 ✓ Starting... Error: "next start" does not work with "output: export" configuration. Use "npx serve@latest out" instead.

What I believe is happening:

• Since I’m using static export (output: 'export'), next build is generating an out/ directory.

• But my Dockerfile or package.json is using next start, which only works with server-rendered apps.

Question:

What’s the best way to configure a static-only Next.js app with output: export to run properly on Railway?

Do I need to:

• Replace next start with serve out?

• Adjust my Dockerfile accordingly?

• Switch to the Railway Static project type instead of a container?

Any advice or examples would be appreciated!

Thanks
