Ensure occurs while duplicating world partitioned level by WorldPartitionRenameDuplicateBuilder commandlet

The level seems to have been successfully copied.

1. Create a project
2. Create a level with OpenWorld template
3. Save the level
4. Quit the editor
5. Run WorldPartitionRenameDuplicateBuilder
   Example command line is :

   [uprojectpath] [CreatedWPLevel path] -run=WorldPartitionBuilderCommandlet -SCCProvider=None -builder=WorldPartitionRenameDuplicateBuilder -NewPackage=/Game/Dest/Map1
   

Result:

Ensure condition failed occurs with the log :
