Connect-HTTP does not accept request parameter with % symbol



After upgrading to Pega 7.2.2, IllegalArgumentException occurs when a % symbol is passed into the request parameter through the Connect-HTTP. This occurs during integration.

Error Messages

Caught unhandled exception: java.lang.IllegalArgumentException: URLDecoder: Illegal hex characters in escape (%) pattern - For input string:

Steps to Reproduce

Pass the Request with % symbol to Connect-HTTP integration rule

Root Cause

When a '%' symbol is present in the request parameter data value, decoding fails in the invokeHttpConnector. The '%' symbol must be handled correctly and replaced with its encoded value such that decoding passes in the invokeHttpConnector activity.
