How can I get around this error to leverage DocSet forms editing functionality?
We're on Nintex Forms 2013 ( 188.8.131.52 )
I've tried the ootb docset content type, a custom site content type in a standard doc library and the result is the same.
support for document sets wasn't released until version:
Product version: 184.108.40.206
Release date: 22nd November 2017
