checkov.cloudformation.parser.node.TemplateAttributeError: list_node.items is invalid

Hi, I’m running Checkov as part of a pipeline using the ubuntu-latest image and install python 3.7 to run Checkov. I’m getting the following error using the example Github action script:

Traceback (most recent call last):
  File "/opt/hostedtoolcache/Python/3.7.9/x64/bin/checkov", line 5, in <module>
    run()
  File "/opt/hostedtoolcache/Python/3.7.9/x64/lib/python3.7/site-packages/checkov/main.py", line 66, in run

    raise TemplateAttributeError('%s.%s is invalid' % (self.__class__.__name__, name))
checkov.cloudformation.parser.node.TemplateAttributeError: list_node.items is invalid
Error: Process completed with exit code 1.

Github actions:

     - name: Set up Python 3.7
        uses: actions/setup-python@v1
        with:
          python-version: 3.7

      - name: Checkov tests
        run: |
          pip install checkov
          checkov -d .

I’ve tried using pip, pip3, upgrading and also installing setup-tools to help install extra deps. Is there anything else I can do?

To Reproduce Steps to reproduce the behavior:

1. Create a github action with the above script

Expected behavior Checkov runs tests successfully and installs relevant dependencies

Desktop (please complete the following information):

• OS: ubuntu-latest / Github Action container image.
• Checkov Version : latest

Good morning @metahertz ! Hope you’re keeping safe from Covid in Manchester. 😃

Yeah, sure. I’ll send it over. Just received the Slack invite now. Thanks!

@nimrodkor sorry for the delay. I’ve still not tried this out yet and I’m annual leave next week, we can close this if you want as I have a workaround by ignoring those directories but I’ll be sure to try it without ignoring them and reporting back via Slack or something if I do encounter any issues. Thanks!
