[Console] Bulk request fails after indentations are applied

[yuliacech]

There is a problem when sending a bulk request but only when it's formatted in a specific way:

• This bulk request works

PUT /library/_bulk?refresh
{"index":{"_id":"Leviathan Wakes"}}
{"name":"Leviathan Wakes","author":"James S.A. Corey","release_date":"2011-06-02","page_count":561}
{"index":{"_id":"Hyperion"}}
{"name":"Hyperion","author":"Dan Simmons","release_date":"1989-05-26","page_count":482}
{"index":{"_id":"Dune"}}
{"name":"Dune","author":"Frank Herbert","release_date":"1965-06-01","page_count":604}

• After using the button "apply indentations" this request fails

PUT /library/_bulk?refresh
{
  "index": {
    "_id": "Leviathan Wakes"
  }
}
{
  "name": "Leviathan Wakes",
  "author": "James S.A. Corey",
  "release_date": "2011-06-02",
  "page_count": 561
}
{
  "index": {
    "_id": "Hyperion"
  }
}
{
  "name": "Hyperion",
  "author": "Dan Simmons",
  "release_date": "1989-05-26",
  "page_count": 482
}
{
  "index": {
    "_id": "Dune"
  }
}
{
  "name": "Dune",
  "author": "Frank Herbert",
  "release_date": "1965-06-01",
  "page_count": 604
}

• The following error is displayed in the response panel

{
  "error": {
    "root_cause": [
      {
        "type": "x_content_e_o_f_exception",

      }
    ],
    "type": "x_content_e_o_f_exception",

    }
  },
  "status": 500
}

This issue is present in both Ace and Monaco versions of Console.
