Cannot read property _kuzzle_info of undefined

When using the document:search route with the following document body:

{
  "stored_fields": []
}

Kuzzle responds with the following internal error:

 "Error: Cannot read property '_kuzzle_info' of undefined

Also occurs while passing the following property in the search body: "_source": false (works fine with any other _source value)
