Building a ConsoleMe image using Packer - containers

Question

I am trying to build a ConsoleMe image using Packer and I am getting the following error message: Error: Failed to prepare build: "amazon-ebs" 1 error(s) occurred: * Destination must be specified.
How can I solve it?
Below is the template that I'm using for the build
