"TypeError: unsupported operand type(s)" error when testing a Panther-managed detection


When testing a Panther-managed detection, I am getting a TypeError: unsupported operand type(s) error.


Update your local system (or the environment where you are conducting PAT tests) to Python 3.9. 

If you are still receiving this error after updating, please contact Support.


This error is caused when your system is running an outdated version of Python. To resolve this, we recommend updating to the latest version of Python, specifically Python 3.9. Certain operator types can generate errors if your Python installation is not up to date. By updating to Python 3.9, you should be able to overcome these issues.
