Pega 24.2 Blueprint Import Failure – "Create new record failed: Branch ruleset not created"

We are currently creating a new application using Blueprint in Pega 24.2. Our existing application is built on the UI Kit architecture, while the new application is being created using Constellation.

During the Blueprint import process, we are encountering the following error:

“Create new record failed: Branch ruleset not created”

Background:

  • Existing application: UI Kit based
  • Pega version: 24.2
  • New application: Generated through Blueprint and based on Constellation architecture
  • Issue occurs during Blueprint import/application creation

Could you please help us understand:

  1. What could be causing the branch ruleset creation failure during Blueprint import?
  2. Are there any prerequisites, permissions, or ruleset configurations that need to be verified before importing a Blueprint-generated application?
  3. Is there any known limitation or compatibility consideration when creating a Constellation application in an environment that already contains UI Kit-based applications?
  4. Are there any logs, diagnostic steps, or reference documents that can help us troubleshoot this issue?
