For anyone having the error message above, please amend your Makefile by replacing:
cookiecutter -f --no-input --config-file instance.yaml gh:plone/cookiecutter-zope-instance
by
cookiecutter -f --no-input -c 2.1.1 --config-file instance.yaml gh:plone/cookiecutter-zope-instance
Also, take a look and (if you are willing to) work on the Issue.
Cheers,
