[chef] oc-id on chef server 11.1.x? for private Supermarket

Hi. I'm exploring running a private Supermarket. tl;dr -- can I run oc-id on 
our
chef 11.1.x server and point Supermarket at it? Or do I need to spend my time
upgrading to chef server 12?

Thanks!

This doc suggests chef server 12 for oc-id, but doesn't say 11.x is out of the
question: 
https://www.chef.io/blog/2015/04/21/setting-up-your-private-supermarket-server/

This deprecated repo mentions chef server >= chef server 11.2:
https://github.com/chef/oc-id

I tried following the instructions in the doc, and added the config bit to
chef-server.rb:

chef-server]# tail -5 chef-server.rb
oc_id['applications'] = {
  'supermarket' => {
    'redirect_uri' => 
'https://supermarket.redacted.internal/auth/chef_oauth2/callback'
  }
}

But, fail:

chef-server]# /opt/chef-server/bin/chef-server-ctl reconfigure
