Description
Describe the bug
During sonar scanning, some python file raises a NullPointerException with too many conditional IF, ELSEIF or ELSE statements :

It seems that variablesParentLevelMap is null.
Could you check if this is a bug in the rule or develop a fix?
To Reproduce
Steps to reproduce the behavior:
Run the scanner on a python file with too many IF/ELSE statements
