[chef] Chef Metal Destroying Instances - undefined local variable or method `iam_endpoint'

[Douglas Garstang < >]

I'm trying to destroy (delete? some docs say it's 'destroy' while other say 'delete') EC2 instances started with chef-metal.

Here's the destroy recipe, pretty simple:

require 'chef_metal'
with_chef_server "https://chef01.prod.slicetest.com:443", {
  :client_name => Chef::Config[:node_name],
  :signing_key_filename => Chef::Config[:client_key]
}
machine "mongo-cfg01.dev-volatile.slicetest.com" do
    action :destroy
end

and here's what I get when I run it:

================================================================================
Error executing action `destroy` on resource 'machine[mongo-cfg01.dev-volatile.slicetest.com]'
================================================================================

NameError
---------
undefined local variable or method `iam_endpoint' for ChefMetalFog::Providers::AWS:Class

Resource Declaration:
---------------------
# In /Users/doug/git/chef/chef-metal/mongo-dev-volatile-down.rb

  9:     machine "mongo-cfg01.dev-volatile.slicetest.com" do
 10:         action :destroy
 11:     end
 12: #end

Can't get much simpler than that. What am I doing wrong?
