I am trying to execute bulk query using Postman but getting an Error

Elastic Stack Elasticsearch

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}

I am getting one error :

{
    "error": {
        "root_cause": [
            {
                "type": "illegal_argument_exception",
                "reason": "Malformed action/metadata line [1], expected START_OBJECT but found [START_ARRAY]"
            }
        ],
        "type": "illegal_argument_exception",
        "reason": "Malformed action/metadata line [1], expected START_OBJECT but found [START_ARRAY]"
    },
    "status": 400
}

Could you try the same thing in Kibana?
It looks good to me.

Is it EXACTLY what you are sending?

Yes, Its working properly in Dev Tool but in our scope, we want to execute it in Postman.

You need to make sure that Postman converts the request to something like:

$ cat requests
{ "index" : { "_index" : "test", "_id" : "1" } }
{ "field1" : "value1" }
$ curl -s -H "Content-Type: application/x-ndjson" -XPOST localhost:9200/_bulk --data-binary "@requests"; echo
{"took":7, "errors": false, "items":[{"index":{"_index":"test","_id":"1","_version":1,"result":"created","forced_refresh":false}}]}

See the application/x-ndjson part...
