Steps to Reproduce

Whenever we try to complete an assignment. 

Root Cause

A defect in Pegasystems’ code or rules. The pyPopulateCaseContents activity uses the pyWorklistAssignmentsDefinition Report Definition (RD) to retrieve non-internal Flow Assignments. However, internal assignments are also returned from the PZINTERNALCASEFLOW flow but these cannot be processed here.

Resolution

Referred  PDN link.
https://pdn.pega.com/support-articles/stringindexoutofboundsexception-when-submitting-flow-action

And performed the following local-change:

The pyWorklistAssignmentsDefinition RD is used to retrieve the assignments list for a given case.

1. Add a Column "pxSystemFlow" in the RD which determines if the flow is internal or not
2. Add filter condition pxSystemFlow set to false which excludes internal flows.
