What happened?

When storing an aws-ecs step in OCL, and specifying environment variables for the container, Octopus will throw the following error when attempting to load the deployment process:

System.InvalidOperationException: Sequence contains no matching element

Reproduction

1. Create a git project
2. Create a step using the aws-ecs step package
3. Specify environment variables for the container
4. Commit the deployment process
5. Attempt to get the deployment process via Octopus
6. 💥

Example OCL:

step "Deploy Service ECS" {
    action {
        action_type = "aws-ecs"
        step_package_version = "1.3.0"

        inputs {
            containers {
                containerName = "foobar"

                environmentVariables {
                    key = "MY_ENV_VAR"
                    type = "plain"
                    value = "my value"
                }
            }
        }
    }
