Hi. How does the option look like? Most likely you must give a list of domain names enclosed in brackets. See “foreman-installer --scenario katello --help | grep proxy-dhcp”
There is no scenario puppet. Just run foreman-installer
# foreman-installer --help
or even
# foreman-installer --full-help
In your case, running foreman-installer with --reset-foreman-proxy-dhcp-option-domain should reset the option to it’s default value, which should be (["example.com"]) with your domain instead.
