Hey guys,

I'm following the PDG Tutorial 2 from the official docs -
https://www.sidefx.com/docs/houdini/tops/tutorial_pdgimagemanipulation.html [www.sidefx.com]

I'm on Part 3 of the guide (Part 3 - Assemble images into a video) but it seems like the python expression:
len(pdg.workItem().outputFilesForTag('file/image')) < 10

on the Filter by Expression node is not working. No work item is being generated by the node. I also check the final working file from the pdg_examples directory - top_imagemanipulation.hip and its the same result, no working item when trying to cook.
