Tracer stops working on tracing a service rule



Tracer stops working on tracing a service rule (Service SOAP). This occurs post upgrading to Pega 7.4. Step, parameter and local variable properties or pages do not open on Tracer.

A few Tracer events, including those related to services, do not contain data such as parameters or information about the primary page and sometimes errors occur on opening the details.

Error Messages

Not Applicable

Steps to Reproduce

  1. Open a service rule (Service SOAP)
  2. Click the Trace this rule option
  3. Click a step
  4. Verify a parameter and local variable properties 

Root Cause

A defect in Pegasystems’ code or rules. Issue with the selection of SOAP Messages events in the Service Trace.


Apply HFix-54389.
