Lunch box error

Whenever i try to add panel to my structure it shows this error

Warning: One or more of the input types are not matching. Couldn’t find a version of ByPoints that takes arguments of type (__array,Revit.Elements.FamilyType)

can anyone help me with this ?

is your input to points a list of lists? aka multi level list? try toggling the input to use levels.
