Root Cause

An issue in the custom application code or rules: The new application ruleset stack failed to validate due to the presence of a duplicated ruleset in the generated stack. 
The ruleset YourRuleSet  was present with two versions (01-01 and 01-02) in the generated stack. Version 01-02 was the latest version available and the only one to be expected in the stack.


Perform the following local-change:
  1. Inspect the built on application rulesets prerequisites and their descendants to ensure that only one version of ruleset YourRuleSet is referenced.
  2. Update any reference to other versions of the ruleset to the expected version.
