Revit API收集器：无法强制转换值：空格到目标类型：

Question

我不明白为什么我的代码适用于其他revit类别：

# -*- coding: utf-8 -*-
import rpw
from rpw import revit, db, ui, DB, UI

dd1 = rpw.db.Collector(of_category='Spaces') 

产生此错误：

什么目标类型？如果您的目标类型是房间，则说明由The Building Coder对Collecting all Rooms on a Given Level的讨论提供：您不能直接收集Room元素，因为它们是Revit API的人工构造，不存在于Revit内部。因此，您需要收集SpatialElement对象，而不是Room父类，并对结果进行后期处理，例如，将它们强制转换到文件室。另见Accessing Room Data和Filtering for a Non-Native Class。你知道吗
