Cannot create custom group heatmaps

[txapel91]

When I try to create a heatmap for a few groups I get the error "TypeError: 'NoneType' object is not iterable"
I use the syntax python dettect.py g -g 'group1','group2','group3'

Has there been a change in syntax needed?
This used to work in the past.

Here is the excerpt from the command:

hi @txapel91

Thank you for reporting this issue. Your syntax is correct! After investigation I found out that since the latest ATT&CK release something changed in the STIX objects that lead to this error. I just fixed it and you should now be able to run your command.

cheers,
