Pinning markupsafe, see discussion I had error:

jinja2/filters.py", line 13, in <module>
    from markupsafe import soft_unicode
ImportError: cannot import name 'soft_unicode' from 'markupsafe' (/home/alex/anaconda3/envs/pulumi_env/lib/python3.10/site-packages/markupsafe/__init__.py)

fix pip install markupsafe==2.0.1
