Hey all, we got some issues with our dagster deployment. We are following https://docs.dagster.io/deployment/guides/kubernetes/deploying-with-helm and run it in a AWS EKS cluster with user deployments. Yesterday I built a new version of the user deployment container image, but now the container does error out with the error

Traceback (most recent call last):

    from markupsafe import soft_unicode
ImportError: cannot import name 'soft_unicode' from 'markupsafe' (/opt/venv/lib/python3.8/site-packages/markupsafe/__init__.py)

I tried to pin markupsafe by adding

RUN pip install markupsafe==2.0.1

to the Dockerfile, but without success. Strangely when i launch into the container and try to do the import

from markupsafe import soft_unicode

I dont get an error. Does anyone have an idea what the issue could be?

not sure if there's a better versioning fix here, but it looks like the exception might be coming from within a virtual environment at /opt/venv - do you maybe need to source that environment before pinning markupsafe? something like

RUN source /opt/venv/bin/activate && pip install markupsafe==2.0.1

This should have been fixed in 0.14.1 - https://docs.dagster.io/changelog#0141

Hi. You can try after downgrading to markupsafe=1.0.1 OR upgrade it to MarkupSafe=2.0.1
