Special Characters are interpreted incorrectly when using JSON



Special Characters are interpreted incorrectly when using JSON.

Error Messages

Not Applicable.

Steps to Reproduce

Pass the below special characters in REST or JSON request.
  • /
  • &
  • < >
  • %

Root Cause

A defect or configuration issue in the operating environment. The parser was not enabled to parse special characters. This is not enabled by default because it increases the CPU footprint of the parser.


Perform the following local-change:

  1. Add the following Dynamic System Setting (DSS):
    DSS name : json/escapeSpecialCharacters
    Owning ruleset : Pega-IntSvcs
    Value : true
  2. Restart the system
