How to send request with bulk? Elasticsearch

Question

I have an object with data, and i want to send this data to elasticsearch container

      for(let key in params)
               {
                  bulk.push(JSON.stringify({
                index: {
                    _id: params[ key ][ 'id' ],
                    _type: 'id',
                    _index: 'geo'
                }
            }));
            bulk.push(JSON.stringify(params[key]));
        }
        let bulks = bulk.join("\n") + "\n";

I made request

let cat =  request(
    {
        'method' : 'PUT',
        'uri'    : 'http://dev4.int10h.net:40024/_bulk',
        'body'   : bulks ,
        'json'   : true,
        'headers':
            [
                'Content-Type: application/x-ndjson'
            ],
        'agent'  : false
    }
);

but has error

Unhandled rejection StatusCodeError: 400 - {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"The bulk request must be terminated by a newline [\\n]"}],"type":"illegal_argument_exception", "reason":"The bulk request must be terminated by a newline [\\n]"},"status":400 } at new StatusCodeError (/usr/lib/node_modules/request-promise/node_modules/request-promise-core/lib/errors.js:32:15) at Request.plumbing.callback (/usr/lib/node_modules/request-promise/node_modules/request-promise-core/lib/plumbing.js:104:33) at Request.RP$callback [as _callback] (/usr/lib/node_modules/request-promise/node_modules/request-promise-core/lib/plumbing.js:46:31) at Request.self.callback (/usr/lib/node_modules/request/request.js:185:22) at Request.emit (events.js:182:13) at Request.

How to properly send bulk?

bulks type string

Answer 1

Not sure if this helps you but here I found similar problem with _bulk and JSON.stringify .

The answer is:

It looks like the meta characters in your payload does not get translated into newlines. If you instead used the elasticsearch.js client, it would handle this for you.
