Why am I receiving the invalid assignment type error?
I am using the ArcGIS Notebooks supplied on GitHub to add assignments to a Workforce project via CSV.
I used the sample csv and added a field called assignment_type to store the GUID for each assignment.
When I upload the CSV, I received ValidationError: Invalid Assignment Type
The CSV successfully loads

I've updated the Notebook to retrieve the assignment_type just like the other columns.

I've even tried assignmenttype (which is the actual field name in the assignments layer)
Thanks for your help.
