docling-serve exits with error code 3 after starting all services

[nixonhanna]

I’m setting up OpenRAG on macOS and followed the getting started steps. All services start, but docling-serve exits immediately with error code 3.

My question
What usually causes docling-serve to exit with code 3 in an OpenRAG setup?

I’d appreciate help with:

what this exit code mean in this context
Which logs or config should I inspect first
whether there are common missing dependencies, environment variables, or path issues that cause this

I had to start it manually using this command uv run python scripts/docling_ctl.py start --port 5001
