The agent gets stuck without any further prompt after this error.
I have tried updating the playwright within the docker file before running this but the issue still persists.
RUN pip install pytest-playwright playwright -U --break-system-packages
Any suggestion to fix this issue?

@Sridhar701Pitt I'm stuck here to is this a Microsoft Playwright version problem? I have fount this issue on Playwright github PlaywrightGitHub
It seems like the Docker image messes a bit around with Linux user accounts. It has some special user called nonroot. And root's home directory is /home/nonroot which seems against any Linux best practise.
How did I fix it?
Change devika.dockerfile user to root
FROM debian:12
# setting up os env
USER root
WORKDIR /home/nonroot/devika
ENV PYTHONUNBUFFERED 1
ENV PYTHONDONTWRITEBYTECODE 1
# setting up python3
RUN apt-get update && apt-get upgrade
RUN apt-get install -y build-essential software-properties-common curl sudo wget git
RUN apt-get install -y python3 python3-pip

RUN $HOME/.cargo/bin/uv venv

ENTRYPOINT [ "python3", "-m", "devika" ]
@mufeedvh I fix it with root user on docker. Because no root user causes this problem https://github.com/hqnicolas/devika/blob/main/devika.dockerfile
