Domain now required in Host Group in order to register via bootstrap?

Last week I rebuilt my test sat 6 server. It is now v 6.2.2, prior to that it was 6.2.1 and the bootstrap worked fine to register systems, minus it installing puppet agent even with the arg not to; I did not have a Domain listed in the Host Group because I feel it is not a necessity and the bootstrap did not complain.

Today I use the bootstrap.pl with the same options as I have used prior:

./bootstrap.py -l admin -p password -s satserver.example -o 'Default' -L 'Default' -g Default -a 'Default' --skip-puppet

And now receive this error:
