Issue

When creating JSON using the Append and Map feature in a data transform, if the source Clipboard data contains nested Page Lists, nested data beyond the 2^nd level is not contained in the JSON. 

Symptoms and Impact

jsonData parameter output does not include the expected nested data. 

Steps to reproduce

1. Create a data transform. 
2. Add a step that uses the Append and Map to action to map a clipboard page to An array of objects. 
3. Create a complex clipboard page with nested Page Lists. 
4. Execute the data transform to pass the complex clipboard page to the Append and Map to step.

Root Cause

A defect in the Pega Platform^TM which results in nested page structures not being included in the JSON.

• Pega Platform 23.1.3
