Encountering this exact error when trying to craft a stack of items by shift-clicking the resulting item in a remote controller.
The item has polymorph alternative available

After crafting one set (6 fences) of said item, the polymorph icon and resulting item icon disappeared. Shift clicking on the now empty result window successfully crafted entire stack of items.
