Started getting this recently in Nuke when trying to open a work file from another user’s sandbox (and the open fails):
"e:\bottleship\code\btltest3\install\app_store\tk-multi-workfiles2\v0.13.1\python\tk_multi_workfiles\actions\interactive_open_action.py", line 83, in execute
if self.file.version < max_local_version:
TypeError: '<' not supported between instances of 'int' and 'NoneType'
I cannot attribute it to a specific update (we hadn’t updated in a while before, did not get fixed after updating apps and core now).
It appears that the list of versions for the given workfile is empty.
