title: creating a geojson file for itunes
body: <p>I would like to add to my app the routing app coverage file, I create a geojson file:</p>
  
  <pre><code>{"type":
  "MultiPolygon","coordinates":[
      [-1.897287,39.035986],
      [-1.862268,39.022384],
      [-1.841154,39.000643],
      [-1.831369,38.980829],
      [-1.862869,38.967084],
      [-1.887503,38.976226],
      [-1.899261,39.007379]
  ]
  }
  </code></pre>
  
  <p>But I got an error:</p>
  
  <pre><code>JSON file you uploaded was invalid. Errors : Each set of coordinates provided must be valid : [Ljava.lang.Object;@7de9b790
  </code></pre>
  
  <p>What is my mistake?</p>
  
  <p>Thanks!</p>
