[Bug]: Nixpack doesn't seem to detect required config

[aschenkuttel]

Error Message and Logs

Framework: Remix.js

My application won't run. Logs only display caddy since it will run instead of my application as the first process if I understood that correctly.

Workaround is simply setting "npm run start" manually as the start command.
This fixes everything.

Is that nixpack related or how coolify implements them?

Steps to Reproduce

1. Deploy
2. caddy output in logs
3. set npm run start manually
4. restart

I can confirm this happens with my react-router-v7 application.
Setting the start command to "npm run start" instead of the default empty fixes it for me as well.
This happened on 4.0.0-beta.395 and now on 4.0.0-beta.397
