Error occurs when running the OOTB WordEmbedMergeTest flow



Unable to merge the correspondence generated in Pega 8.1.1. An error displays when running the out-of-the-box WordEmbedMergeTest flow.

Error Messages

Failed to (re)attach Process Commander session.

Steps to Reproduce

Use the WordEmbedMergeTest flow to generate  a document after loading SilverLight.

Root Cause

The issue occurred because encrypted cookies were enabled by default from Pega 8.1 onwards.


Perform the following local-change: 
  1. Verify the Location Records > SysAdmin > Dynamic System Settings (DSS).
  2. Filter under Owning Ruleset Pega-Engine.
  3. Search for the prconfig/initialization/advancedSession/default Setting purpose. 
  4. If the Setting purpose is unavailable, create it and set its value as False. If the Setting purpose is already available, then change its value to False.
  5. Save the settings.
  6. Log out and restart the Pega server.
  7. Clear the browser cache and Temp files from the user's system.
  8. Search for the file name from the client system and delete it. Retest the scenario.
