title: parsing json to POJO using retrofit
body: <p>I am trying to parse json to a POJO using retrofit, but keeps getting an error. 
  It seems to get the data and as far as I can see from the logcat i reads and parses the json correctly. But it returns succes=false and do not return a responsedata object. 
  The error type and error message reads null.
  I have no idea of what is wrong and would appreciate any suggestions to solutions or how to locate the error.</p>
  
  <p>Json</p>
  
  <pre><code>{
    "competition_info": {
      "headline": "competition",
      "description": "description for competition.",
      "accept_button": "OK",
      "open_terms_button": "Open info"
    },
    "terms": {
      "html": "a website in html"
    }
      }
  </code></pre>
  
  <p>MyPojo</p>
