Elasticsearch: Bulk request throws error in Elasticsearch 6.1.1

Question

I recently upgraded to Elasticsearch version 6.1.1 and now I can't bulk index documents from a JSON file. When I do it inline, it works fine. Here are the contents of the document:

{"index" : {}}
{"name": "Carlson Barnes", "age": 34}
{"index":{}}
{"name": "Sheppard Stein","age": 39}
{"index":{}}
{"name": "Nixon Singleton","age": 36}
{"index":{}}
{"name": "Sharron Sosa","age": 33}
{"index":{}}
{"name": "Kendra Cabrera","age": 24}
{"index":{}}
{"name": "Young Robinson","age": 20}

When I run this command,

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

I get this error:

"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

It works fine if I send the data inline and in Elasticsearch 5.x. I tried adding newlines as well as the newline character to the end of the file. Doesn't seem to work.

Answer 1

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'
