Hello, @TG1999 While testing the Docker-based CI pipeline locally using the act tool, I encountered a ModuleNotFoundError for some dependencies like cvss, django-extensions, and htmllistparse. These modules were used in the codebase but weren’t listed in the requirements.txt file.
As the docker tests use the command docker compose build --no-cache, which will create a new image which doesn't include the modules present in the host or owners machine. So I explicitly added those module.
Thank you for reviewing my PR
