    Description

      As a user, when attempting to add a template from 0.x that contains an RPG to the graph I get a screen saying "unexpected error". After returning to the canvas, all the processors were added to the graph but there are not process groups, connections or remote process groups. In the user logs there is the below exception.

      I believe this is due to the template not having the type of RPG (raw vs http).
