AttributeError: 'NoneType' object has no attribute 'ui_type'

bpy as a python module is headless

There is no ui associated with bpy that is compiled as a python module. Objects like screen area and region are part of the UI which being non existent, are given the value None.

  • $\begingroup$ IMO Not the same, a render is an image, using the 3d viewport involves opening blender, exporting to some other format that has a viewer app is another option. For using blender, perhaps the suggestion by @rob in your similar question re setting up a client server and feeding the opened blender your scripts (especially if you want to manipulate the UI) rather than using the bpy module. $\endgroup$
