Elasticsearch: Bulk request throws error in Elasticsearch 6.1.1

As the document says: use the --data-binary flag instead of plain -d

-d doesn’t preserve newlines and doesn't format the json.

I faced this problem because of JSON formatting.

The error is pretty clear:

The bulk request must be terminated by a newline [\n]

So you simply need to add a newline at the end of your customers_full.json file and you'll be ok.

Add empty line at the end of the JSON file and save the file and then try to run the below command

curl -XPOST localhost:9200/subscribers/ppl/_bulk?pretty --data-binary @customers_full.json -H 'Content-Type: application/json'
