Creating face-based family

I am trying to create a few face based generic model families. GH is giving the below error:

Here is the selected geometry:

The same definition using the Mass template worked to create a mass family but I want to create a generic model (or specialty equipment, etc).

Here is the internalize definition.

Thanks for any help.

I managed to fix this by selecting the template file rather than using a panel.

How do I place it at the origin of the family?

Fixed by moving to origin of rhino document in Gh

ahh… actually I can only get one to run.

Ok, I was able to move forward by creating a new family component from scratch for each family to be created, rather than copy and pasting the group of components. This seemed to be causing an error.
