AttributeError: 'IntegrationTest' object has no attribute 'attack_data'

Hi, when running contentctl build --verbose, I get this weird error:

C:\Users\user\.virtualenvs\something\Scripts\python.exe -m contentctl.contentctl build --verbose 
INFO: Common Information Model/CIM (uid: [1621]) is not listed in apps.
contentctl test MUST include Common Information Model.

There seems to be a problem with the parsing in Detection_Abstract.validate_test_groups().
It looks like a logic error, where the code assumes it’s a UnitTest object but receives a IntegrationTest object.

Any idea?
