zpy.output_zumo.ZUMOParseError: width and height h:0 w:0 must be > 0

Describe the bug In Blender v2.91 and zpy v0.9.10 I got following error when I run Suzanne 3 demo run.py:

All data is generated, so it looks like a minor bug.

Expected behavior No errors when any of demo is run on released zpy version.
