Hatch Explode - reference extended geometry

Hi there,

I have been trying to use the extended geometry to reference hatches and plug them into the Hatch Explode component.
However, the Hatch Explode comment returns an error of “1. Solution exception:Object reference not set to an instance of an object.”. Whereas the hatch I am plugging in through extended geometry is recognised as a rhino hatch object.

Anything I am doing wrong?

Many thanks
