responseTemplate and top-level arrays

I’m having some trouble parsing JSON using responseTemplate. The responses I’m getting look like:

[
  { "status" : "stuff" },
  { "status" : "things" }
]

…and my webhook.json looks like:

{ 
  "event": "develop_builds",
  "url": "https://circleci.com/api/v1/project/teespring/rails-teespring/tree/develop?circle-token=<mine>",
  "requestType": "GET",
  "headers": {
    "Accepts": "application/json"
  },
  "responseTemplate": "{{#.}}{{status}}{{/.}}",
  "mydevices": true 
}

it works in the mustache online test app, but I’m not getting anything back when I call the webhook. Anything. The response function isn’t even being called. :frowning:

Any guess what might be going on or how I can debug it?
