Hi,

Could you please try to install "libgl1 and libglib2.0-0" in your venv?
cmd: apt-get install -y libgl1 libglib2.0-0

I added this to Dockerfile

FROM langflowai/langflow:latest

USER root

RUN apt update && apt install -y libgl1 libglib2.0-0

CMD ["python", "-m", "langflow", "run", "--host", "0.0.0.0", "--port", "7860"]

Then used the docker-compose.yml in docker_example folder. Just added this line in langflow service
user: root

When I launch docling in langflow and run the flow, I still get

Error building Component Docling:
libGL.so.1: cannot open shared object file: No such file or directory
