Issue/Introduction

A PX Policy has been migrated into a new environment and is now failing to fire with a missing parameter error. 

Environment

Release:
Component: IDMGR

Cause

What this error means is that in your "data" tab of the PX Policy, a parameter that is referenced does not exist in the environment. This can happen if the PX is migrated from another environment and they have different attributes. 
 

Resolution

To resolve the error, review all of your data elements and ensure that the referenced attributes exist in your environment.
