Being not that fluent in Python I can't say if I'm doing something wrong or it's a plain incompatibility of this app with Django 4.2 and Python 3.11.5 (or Wagtail CMS in my case).
My fields (as in the readme example) implemented in Wagtail's 5.1.2 model:
when filled the date_edtf field with value (let's say 1800 or 'Fall 1989') I get a TypeError: object of type 'Unspecified' has no len().
Thanks for any hints.
