Add Project Parameter not added to Subcategories

Hi :slight_smile:
I´ve got a problem with the “Parameter.AddProjectParameter” Node from Orchid. It´s supposed to create a Parameter for every Category when the “category” input is left empty, but it doesn´t include subcategories.

When I try to create a list of categories / subcategories and put this into the input the node creates an error. Does anyone have a workaround for this?
