Error when copy/saving workflows which include some Harp operators

[ChucklesOnGitHub]

Hi I'm trying to visualize the timestamp from a digital input on the harp behavior board and one on the input expander, for a demo.

They each work independently, but I get errors when I try to combine them, if I try to cut/copy or save.

I've isolated that the errors appear when I add the HasFlag operator:

I also get an error when I add the RollingGraph panel:

My workflow is attached:
demo_2.9_behavior_inputexpander_sync_new_half-baked.zip

I uninstalled and re-installed the packages, and then worked in a new environment, but no luck.
Any help is appreciated.
