anyone know Celigo Integrator.io well? We're trying to un-assign hundreds of thousands of items from an old Merchandise Hierarchy. This is my first time messing w/ a Merchandise Hierarchy feature of NS. What I'm trying to do is uncheck the "Include in Version" boolean box on the item record, for each item that comes up in a saved search we made. For this example I'm using 1 item. I've tried just about every mapping I can think of here but it keeps giving me this error which I can't seem to figure out why "Failed to create, update/transform record because You have attempted an invalid sublist or line item operation. You are either trying to access a field on a non-existent line or you are trying to add or remove lines from a static sublist. Tip: Please make sure that all the line items that you're trying to use exist on the record."

You need to map a line reference as well. Otherwise it will not identify which line to update.

Thanks @Selcuk Dogru I tried that prior to posting but unfortunately no luck there. Here's the mapping, and I told it in the import that we're looking for Internal ID.
