Issue

When using the Service Level Agreement (SLA) Queue Processor (QP), queue items enter a broken state if the Activity-End method is invoked in the EstablishContext activity. The broken queue items reference the following error:

Caused by: com.pega.pegarules.pub.runtime.ActivityTerminateException: PRRuntimeError
at com.pega.pegarules.session.internal.mgmt.Executable.terminateActivity(Executable.java:3815)
at com.pegarules.generated.activity.ra_action_establishcontext_5d104e556daf03efe1c94f6776d7b4b0.step3_circum0(ra_action_establishcontext_5d104e556daf03efe1c94f6776d7b4b0.java:572)…

This error does not occur when using the SLA agent.

Steps to reproduce

1. Set the UseSLAQueueProcessor Dynamic System Setting to “true”.
2. Create a case type which uses at least one SLA.
3. Create a case of that case type and process it until it is queued for the SLA Queue Processor.

A processing error occurs and subsequently triggers the Activity-End step in the EstablishContext process. 

Root Cause

A defect in the Pega Platform causes the Activity-End step to create a broken queue item when it returns an ActivityTerminateException. This issue can occur in various scenarios, including, but not limited to, instances where an assignment is unexpectedly missing when the SLA queue item is picked for processing.

Solution

Update to the following Pega Platform version with the fix:

Pega Platform 24.2.2, see Pega Platform 24.2.2 Patch Resolved Issues.
