Integration Response cannot map array of items

My goal is to to be able to produce a csv file. For now just trying to return a list of ids in JSON.

I'm struggling to map a response, so my JSON is: 

{
"items": [
        {
            "id": "2017-07-02_n_Eleana Qorgyle",
            "groupId": "n_2017-07"}
]
}

and my model is 

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "title": "Log",
  "type": "object",
  "properties": {
    "items": {
      "type": "array",
      "items": {
        "type": "object",
        "properties": {
          "id": { "type": "string" }
        }
      }
    }
  }
}

My Velocity template is ...

#set($inputRoot = $input.path('$'))
{
  "items" : [
##TODO: Update this foreach loop to reference array from input json
#foreach($elem in $inputRoot.items)
 {
    "id" : "foo"
  } 
#if($foreach.hasNext),#end
#end
]
}

However, I am getting this output: 

{
    "items": []
}

Have I missed something? $inputRoot.body outputs everything, but iterating is an issue.

I think this is what you are trying to do:

  #set($inputRoot = $input.path('$')) {
      "items" : [
       #foreach($elem in $inputRoot.items){
        "id" : "$elem.get('id')"
       } 
       #if($foreach.hasNext),#end
       #end
      ]
   }

Thanks!
