Unable to Populate Data Model with Asset Hierarchy

Hi guys,

 I’m facing an issue while trying to populate a data model and create a hierarchy of assets. Despite following the steps outlined in the microlearning materials step-by-step, I am unable to visualize the asset hierarchy in the data model.

It appears that the hierarchy is not being created, even though the process runs without errors.

For reference, I have attached the transformation I used to populate the data model.

I created the space "DnI-Assets” and the target was the Cognite Core model and Cognite Assets.

I can see those assets within the data model > Cognite Core > Cognite Assets instances. But not the Hierarchy itself.

I'd like to see the assets hierarchy and the graph views. Any idea how to solve this? 

Best regards,
Daniel
