I am deploying a FastAPI application directly from my GitHub, and I have validated that it builds properly and works locally. Weasyprint isn't working through Railway, and I've tried troubleshooting through some existing threads. I am not installing and configuring through Docker like these, and I'm wondering if Docker is the only way to resolve this.

I have also tried setting my NIXPACKS_PKGS=libgobject-2.0-0 libcairo2 libpango-1.0-0 libgdk-pixbuf2.0-0 libffi-dev per https://station.railway.com/questions/cant-install-weasyprint-dependencies-d742101d, and that has not worked. Thanks!
