As per the tutorial

import os


buildings_path = hou.node(“.”).parm(“path_to_buildings”).eval()
buildings_folder = os.listdir(buildings_path)

print buildings_folder


returns following error


Error running callback:
Traceback (most recent call last):
File “<stdin>”, line 1, in <module>
File “<string>”, line 4, in <module>
AttributeError: ‘NoneType’ object has no attribute ‘eval’

Also noted the tutorial file supplied as a checkpoint also shows this error so how would I carry out this task of listing the folder directory.

best regards
