Robot unresponsive when triggered from a flow action



On entering special characters (for example, carriage return, ':', ';', and '-' ) and clicking the Fix by Automation button during run time, the system does not respond when using Pega Robotics Studio 8.0.

Error Messages

Not Applicable

Steps to Reproduce

  1. Configure a flow action to start a section that contains a simple text area
  2. At run time, enter special characters in the text area and click the Fix by Automation button

Root Cause

A defect in Pegasystems’ code or rules. The JSON data received from the system contains carriage return characters (\n, \r, \t). While parsing the data with special characters, parsing issues occur with JSON parse APIs.


Apply HFix-32929 and HFix-35311.
