Running docker container doesn't work

[vexleet]

Hi.

I have the playwright crawler example https://crawlee.dev/python/docs/examples/playwright-crawler and want to run it with docker, but when I try, I get RecursionError: maximum recursion depth exceeded.

This is my dockerfile:

FROM python:3.9.20

WORKDIR /app

COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt && \
    pip install 'crawlee[playwright]' && \
    playwright install --with-deps chromium

COPY . .

ENTRYPOINT ["python", "main.py"]

And this is the full error I get:

Hey @vexleet

Thank you for your interest in crawlee.

Are there any additional details or nuances on how you do the container startup?

Since I have been using your dockerfile and am getting errors related to running as root user. But nothing like the above error log

Hey @Mantisus

I tried reproducing the problem again after your comment, but I also get root user errors on version 0.5.2 but on 0.5.1 (the one I have been actually using) it's working, though I had my PC fully restarted on Sunday.

I switched to crawlee JS after creating the issue, but I can try running my old python code in the weekend to see if I can reproduce the issue, since I had another code before trying with a crawlee example and both were returning the error above.

I hope that's fine.

If I can't manage, I can just close the issue.

[Mantisus]

I hope that's fine.

Yes, that would be great. Thanks )
