Issue/Introduction

DLP Agent FlexResponse does not work after upgrade from 15.7 to 15.8.

The same FlexResponse Python plugin script works in 15.7 but does not work in 15.8 Agent.

We observe below errors in the agent finest logs during the execution of the FlexResponse plugin.

Environment

DLP Endpoint Agent 15.8.x

Resolution

The FlexResponse Python script should be updated by the developer to work with the latest 3.8 version as the python encoding format has changed from 2.7 to 3.8.

The Python library versions for both the DLP the agent versions are different. The library was updated in DLP 15.8.

DLP Agent 15.7 has Python library version 2.7 and 15.8 has Python library version 3.8.
