layer.typename is not found?

[siriusi]

There is an error: NameError: Name typename not found when I run this code:

from comtypes.client import GetActiveObject
app = GetActiveObject("Photoshop.Application")
srcDoc = app.Open("E:\\Project\\Page_To_Bar\\images\\MangaTest.psd")
print("type", app.activeDocument.activeLayer.typename)

I sure layer.typename is aviliable in ADOBE PHOTOSHOP CC 2015 JAVASCRIPT SCRIPTING REFERENCE
Can you help me?
Thank you.

typename does exist, instead of comtypes.client, try win32com.client then you should be able to get the typename
