Hey could I get a bit more info about your app? It looks like theres some Procfile issues as its saying.
Railpacks also likes using a railpack.json which you can see here: https://railpack.com/config/file/
You might have more luck using that.
If all else fails, a good ol Dockerfile always works!

Use plan text profile( no yaml)
Set the start command in railway 's ui
If you need yaml then write this
