Resolution

How to fix it:
The problem is being caused by known issue: DBX-4623:
Add-ons are python based and the packaging common .py files and set Path/environmental variables point to their local copy. The issue is when the Python files are pointed from the last installed app. Now this might be ok if all the apps/add-ons on a box are using the same Python version but the problem happens when there is a version mismatch and the .py file is not the expected.”

The solution at this time is to downgrade Proofpoint TA to 1.0.1,
Be careful to downgrade the right Add-on, “Proofpoint TAP SIEM Modular Input” as there may be other Proofpoint add-on/app in use.
