	Ids.Add(UnwrapElement(i).Id)

Solution:
Shoud be import Revit API for detect ElementId

import clr

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import * #use ElementId
from System.Collections.Generic import * #use LIST

if isinstance(IN[0],list):
	els = UnwrapElement(IN[0])
else:
	els = [UnwrapElement(IN[0])]
	
lst_id = []
lst =[]
for i in UnwrapElement(els):
	lst_id.append(i.Id)
icolls = List[ElementId](lst_id)

OUT = icolls
