Unable to set REST URI query parameters as optional



Unable to set REST URI query parameters as optional. The request URI generated in the log displays as a blank string.

Error Messages

Incorrect URL

Steps to Reproduce

  1. Create a Connect-REST with query string parameters connecting to an external service.
  2. Do not set the query string parameters. Check the logs for the generated request URI.

Root Cause

A defect or configuration issue in the operating environment.


Perform either of the the following local-changes: 
  • Set the pySkipBlankQueryParts input parameter value to true in the calling activity rule just before the step which invokes the Connect-REST method.
  • Use the below sample code in a Java step to set pySkipBlankQueryParts parameter value to true in the Parameter page before invoking the Connect-REST rule. 

    ParameterPage pp = tools.getParameterPage(); 
    pp.putString("pySkipBlankQueryParts", "true");
