When POSTing to https://api.intel.com/context/v1/items, I am getting weird errors.

If I set the Content-Type to application/json, I get Bad Request.  If not, I get "No JSON object could be decoded".

Other calls in the context API are working fine.

Multiple parsers tell me it's valid.  My JSON:

{
  "data": {
    "items": [
      {
        "contextType": "urn:x-intel:context:type:location:current",
        "value": {
          "latitude": 45.520082,
          "longitude": 122.676103
        }
      }
    ]
  }
}
