Error trying to use Input Form (Publication Template/Content Management)
Hi there,
I created a Publication Template using a schema - input form - javascript template configuration.
I then added the publication template in one of my delivery templates as seen below:

The issue here is that when i then try to use the input form from within the delivery template to edit the email content, i'm getting the below error:

I can't seem to find anything wrong in my schema/form definitions, both seem to be working fine (individually at least), and although i've worked extensively with Publication Templates in the past, i don't recall experiencing this error before.
Schema definition:


Form definition:

Publication template configuration:

Any insight around this would be really appreciated.
Thanks,
Solon
