The above usually indicates there is something wrong with at least one puppet class.
Do you have openstack-puppet-modules installed?

Some of the devil's details:
foreman_server.sh triggers foreman's rake to seed its database.
The nil:NiClass means something is missing and usually when it happens, to be confirmed with rake's trace/logs it's because at least one puppet class is wrong (not validated).
The above is happening because seeding script also parses puppet classes' parameters in order to inject them into Foreman.

Cheers,
