Design tab of the Harness rule is blank



After upgrade from PRPC 6.2 SP2 to Pega 7.1.7 when user opens a Harness rule in Designer Studio, it does not display anything in Design tab. 

Error Messages

Not Applicable

Steps to Reproduce

Open any harness rule. Reported behaviour occurs for OOTB as well as for newly created Harness rules.

Root Cause

The reported behaviour was due to incorrect cache entry. However, similar behaviour also occurs if pzHarnessRuleFormUtils.js file is missing after upgrade from PRPC 6.2 SP2 to Pega 7.1.7.

This JS file is used by the following rule:



1. Truncate all the cache tables and restart the application node.  

2. Export this pzHarnessRuleFormUtils.js file from fresh installation of Pega 7.1.7 by creating product rule and importing it on the environment where the issue occurred. After importing this rule, harness rule is displayed correctly.
