Vagrant and Chef Zero - Missing Role - vagrant

Question

I was happily using Vagrant and Chef Solo, but I read that using Chef Zero will lead to an easier transition to the full Chef Server (something which might happen in the near future of the project). When I started using vagrant plus chef-zero, I get the error during the Chef run, described below.
Vagrant: 1.7.4
Chef(on the guest machine) - 12.4.1
And when I do a $ vagrant up db, this is the output from Chef
==> db: [2015-07-28T09:14:13+00:00] INFO: Chef-client pid: 2525
==> db: [2015-07-28T09:14:14+00:00] INFO: HTTP Request Returned 404 Not Found: Object not found: chefzero://localhost:8889/nodes/db-machine
==> db: [2015-07-28T09:14:14+00:00] INFO: Setting the run_list to ["role[mysql]"] from CLI options
==> db: [2015-07-28T09:14:14+00:00] INFO: HTTP Request Returned 404 Not Found: Object not found: chefzero://localhost:8889/roles/mysql
==> db: [2015-07-28T09:14:14+00:00] ERROR: Role mysql (included by 'top level') is in the runlist but does not exist. Skipping expand.
==> db: Error expanding the run_list:
==> db:
==> db:
==> db: Missing Role(s) in Run List:
==> db: ----------------------------
==> db: * mysql included by 'top level'
==> db:
==> db: Original Run List
==> db: -----------------
==> db: * role[mysql]
This is the relevant bit of my Vagrantfile
machine.vm.provision "chef_zero" do |chef|
chef.node_name = #hostname
chef.cookbooks_path = "#{#chef_repo}/cookbooks"
chef.roles_path = "#{#chef_repo}/roles"
chef.environments_path = "#{#chef_repo}/environments"
chef.environment = #environment
roles.each do |role|
chef.add_role role
end
chef.json = {
"guest_folder_path" => guest_path,
"ubuntu_user" => #ubuntu_user
}
end
When I log in to the virtual machine(db) and go to /tmp/chef-vagrant
$ cd /tmp/vagrant-chef/
vagrant#db-machine:/tmp/vagrant-chef$ ls
2107f3d10c0db9887cdf980054c11e35/ client.rb dna.json
8a1f8968cff1cd79d46fc9ca5bd46931/ df5881620e1c72537e51bddcbc6ceb3a/
vagrant#db-machine:/tmp/vagrant-chef$ cat client.rb
node_name "db-machine"
file_cache_path "/var/chef/cache"
file_backup_path "/var/chef/backup"
cookbook_path ["/tmp/vagrant-chef/df5881620e1c72537e51bddcbc6ceb3a/cookbooks"]
role_path "/tmp/vagrant-chef/2107f3d10c0db9887cdf980054c11e35/roles"
log_level :info
verbose_logging false
enable_reporting false
encrypted_data_bag_secret nil

environment "develop"
chef_zero.enabled true

And this is the content of /roles
vagrant#db-machine:/tmp/vagrant-chef/2107f3d10c0db9887cdf980054c11e35/roles$ ls
mysql.rb
vagrant#db-machine:/tmp/vagrant-chef/2107f3d10c0db9887cdf980054c11e35/roles$ cat mysql.rb

Apparently rb role definitions are not supported in chef zero only JSON ones.
Chef Zero Bug reported
That one is closed but refers to other that is still open.
I have the same problem, so my solution it's going to be to use this gist to translate my roles to JSON and use them that way with vagrant.
