title: Elasticsearch Bulk API - Unexpected end-of-input: expected close marker for ARRAY
body: <p>I'm trying to bulk import using a POST request to <code>localhost:9200/products/product/_bulk</code> with the following JSON:</p>
  
  <pre><code>[
    { "index": {"_index": "products", "_type": "product", "_id": 1} },
    { "title": "Product A","description": "Brand A - Product A - 1.5 kg","price": 3.49,"sku": "wi208564","supermarket": "AJ","categories": "Fruit AJ","product_type": "Sinaasappels - mandarijnen","brand": "Brand A\n"},
    { "index": {"_index": "products", "_type": "product", "_id": 2} },
    { "title": "Product B","description": "Brand B - Product B - 1 kg","price": 2.49,"sku": "wi308564","supermarket": "AJ","categories": "Fruit AJ","product_type": "Sinaasappels - mandarijnen","brand": "Brand B\n"},
    { "index": {"_index": "products", "_type": "product", "_id": 3} },

  ]
  </code></pre>
  
  <p>I keep getting the following error:</p>
  
  <pre><code>{
  "error": "JsonParseException[Unexpected end-of-input: expected close marker for ARRAY (from [Source: [B@2c1e2b0e; line: 1, column: 0])\ at [Source: [B@2c1e2b0e; line: 1, column: 3]]",
  "status": 500
  }
  </code></pre>
  
  <p>I've tried changing the JSON format but it didn't help. What seems to be going wrong? </p>
