SigmaTools sigma2attack errors

[Psyhil89]

Hi,
Recently started getting error while trying to generate heatmap using sigma2attack. Earlier I though it was a python version issue hence tried different python 3, 3.7 upto 3.11, installed sigmatools again but still getting the same error.

python3 sigma/tools/sigma2attack --rules-directory /mnt/c/SIEM/1/ False Traceback (most recent call last): File "/home/sahil/security/sigma/tools/sigma2attack", line 5, in <module> main() File "/home/sahil/security/sigma/tools/sigma/sigma2attack.py", line 69, in main level = rule["level"] ~~~~^^^^^^^^^ KeyError: 'level'

Any guidance on how to fix this?

Thank you in advance!

Found the issue to be because of python version.
Only version 3.9 works with sigmatools.
