Hey @gaborbernat, thanks so much for filing this issue. Helped us debug why our Zappa deployment stopped working.

We are working around it for now by manually installing the last compatible version of virtualenvs and setuptools.

    # Note (Sep 9, 2024): setuptools 74.1.2 breaks imports within site-packages.zip, which causes the zappa deployment
    # to fail. Virtualenv 20.26.3 still uses a compatible version of setuptools. Once this issue gets fixed, we can
    # remove this step.

    - name: Set fixed setuptools version
      run: pip3 install virtualenv==20.26.3 setuptools==70.1.0
