@yamelsenih Please do this. For sphinx<4, errors are occurring with deprecated jinja2 imports:

ImportError: cannot import name 'environmentfilter' from 'jinja2'

Updating sphinx in the Docker file should help resolve this. Feel free to reference my Issue #49 for this if you like.

@ammaraskar Could we update the sphinx base image please?

[watakandai]

I found a workaround for now.

    - name: Build HTML
      uses: ammaraskar/sphinx-action@master
      with:
        pre-build-command: "pip install 'sphinx==7.1.2' --force-reinstall"
        docs-folder: "docs/"

This should upgrade the sphinx version.
