Importing height field from UE4 to Houdini

I'm having some issues importing the height field from UE4 to Houdini, my network is setup like this:
- Created a geo node in a blank project
- Added a HF and a HF noise nose
- Changed the HF noise node to a subnet and saved it to a HDA

I can import the HDA to UE4 and I can select a landscape as the input, but when I cook the asset, there's an error from the Houdini plugin: “Hapi failed: HAPI Error: The node is invalid. Either the otl/hda asset library file was deleted or another otl/hda asset library file was loaded that contained an operator type with the same name as this asset's operator type. You must unload this node's asset and re-instantiate it.”

Am I missing something here?

Your heightfield should be in the subnet
