Root Cause

A defect or configuration issue in the operating environment.

There are three different nodes in the environment.

The rule "pzHarnessRuleFormUtils.js" is not present in one of the node in the environment.


Here’s the explanation for the reported behavior:

Create a product rule for "pzHarnessRuleFormUtils.js" in other environment where issue does not exists.
Truncating the cache tables, importing the product rule package of "pzHarnessRuleFormUtils.js" rule into the node where the file is missing and restarting all the nodes resolves the issue.
