these logs only show the build succeeded but the app never responded to health checks at /api/health ,i cant see why from here. can you share the deploy logs (not build logs)? in railway dashboard go to your deployment and switch to the deploy logs tab, thats where the actual startup error will be

Yes, here are the deploy logs, thanks

the logs you gave show that you passed a negative number "-8000" as one of your environmental variables "port", which caused the error you are seeeing: 2026-03-12T12:23:41.503074232Z [err] Error: Invalid value for '--port': '${PORT:-8000}' is not a valid integer. change "-8000" to "8000"

your entrypoint is passing ${PORT:-8000} as a literal string to uvicorn instead of letting the shell evaluate it. in your dockerfile or entrypoint.sh, make sure the command uses shell form not exec form, so change it to something like uvicorn app:app --host 0.0.0.0 --port $PORT and make sure it runs through a shell so the variable actually gets resolved
