Your error is in this line. Most likely `node['ec2']` is nil, so `node['ec2']['instance_id']` evaluates to `nil['instance_id']` which causes the error.

If you're using EC2 VPC, the cause of your problem is likely this: http://tickets.opscode.com/browse/OHAI-310

Try touching this file: /etc/chef/ohai/hints/ec2.json
