There are a couple of limitations which prevent this from working with Convox at this point, particularly:

- You cannot use the `AWS::CodeDeploy::BlueGreen` hook in a template that includes nested stack resources.
- You cannot use the `AWS::CodeDeploy::BlueGreen` hook in a [nested stack](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-nested-stacks.html).
