Elasticsearch: Bulk request throws error in Elasticsearch 6.1.1 - json

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.


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'


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.


I ran into the same issue and spent hours adding and removing newlines before somebody pointed out I mis-typed the file name... So note that curl will throw the same error if the file is not actually present, making this super-confusing.


I had a similar issue when working with Elasticsearch 7.3.
Here's how I solved it.
Locate the .json file, say products.json file.
Double click to open the .json file in your text editor.
Scroll to the end of the .json file and then press the ENTER key on your keyboard.
Close the .json file. This will create a new line at the end of .json file.
Go back to your terminal and run the command below.
N/B: For the command below, the .json file name is products.json which I am importing to http://localhost:9200/ecommerce/product
curl -H "Content-type: application/json" -XPOST "http://localhost:9200/ecommerce/product/_bulk?pretty" --data-binary "#products.json"
That's all.
I hope this helps


For anyone using postman to make requests to ElasticSearch
Just press enter to create an empty new line!
And voila, problem solved


This worked for me:
curl -H "Content-Type: application/x-ndjson" -XPOST "localhost:9200/bank/_bulk?pretty&refresh" --data-binary "#C:\Program Files\Elastic\Elasticsearch\7.2.0\accounts.json"


I had the same problem running on Windows 10, using ElasticSearch 7.5.1.
I tried all the answers; none of them worked. I was certain I had a newline at the end of my file.
To get it to work, I had to ensure the file I was uploading was using UNIX end-of-line characters (0A only, no 0D), and also the encoding had to be UTF-8.
Using Notepad++, you can edit the metadata of the file.
Finally some good news:


Press Enter end of the line inside the JSON file and run the command again.
curl -H "Content-Type: application/x-ndjson" -XPOST 'localhost:9200/customers/personal/_bulk?pretty&refresh' --data-binary #"generated.json"


I just forgot to add an # symbol before file name like this
--data-binary "#products.json"


you just need to open json file and then go to the end of the file ( Ctrl+end) and then please Enter to break a new line.


I was struggling with this for a hot minute. Mine was caused by a space in my curl request between the --data and the -binary and gave the same error - must end with new line [\\n]}.
So double-check that in the curl req it's --data-binary not --data - binary


For me, the issue was only due to the wrong file name.
I have used customer_full.json in command whereas the file was named customer_full in my file system (without the extension).
So in my case,this command worked for me:
curl -H "Content-Type: application/x-ndjson" -XPOST 'http://localhost:9200/customers/personal/_bulk?pretty&refresh' --data-binary #"customer_full"


I faced a similar issue on windows using elastic 7.9.1 When I used below CURL command.
curl -s -H "Content-Type: application/json" -XPOST localhost:9200/accounts/docs/_bulk?filter_path=items.*.error --data-binary "#textoutES.json" >> erroredAtES.json"
I tried to manually add Newline at the end of the file but did not work.
I have created my JSON by extracting data from MySQL database like below to make sure my records should end with LINE FEED and CARRIAGE RETURN.
Then, it is working for me:
SELECT CONCAT('{"index":{"_id":"',id,'"}}\r\n',request_data,'\r\n') reqestData FROM cards
More importantly you End-of-File should have a carriage-return and Line-Feed (CRLF)if you are using windows. Also if any line in JSON contains a CR but no LF then you will get parsing exception Source: org.elasticsearch.common.bytes.BytesReference$MarkSupportingStreamInputWrapper#2d5ed2ca
Windows CRLF and EOF


You need to use --data-binary instead of -d in your curl request. Please see: Bulk API


This worked in my local set-up.
curl -H "Content-type:application/json" -XPOST "http://localhost:9200/customer/personal/_bulk?pretty" --data-binary #"generated.json"


How do you do that if you are not using a data-file? I am having the issue but not sending data from a file.
const data1 = {
"amount" : "100",
"#timestamp" : `${UTC_timestamp}`,
"transaction_attributes" : {
"channel" : "channel-foobarbaz",
"session_id" : "session-1234",
"information" : "iinformation-foobarbaznformation-foobarbaz"
},
"currency" : {
"currency_description" : "my currency description",
},
"external_timestamp" : "2021-12-03T11:22:55.206229500Z" };
// execute a post
let res = http.post(url,JSON.stringify(data1),params);


A few things to check:
The file ends with new line (\n).
The new line is using Unix eol (LF) and not mac or windows eol.
When specifying the file name in the curl command, make sure "#" was added before the file name.

Error parsing JSON while using Github content API with Curl

I am trying to upload a file to Github using Github content API. Referring docs from the official documentation here.
As per the docs, the data should be base64 encoded before uploading. I have a .tar.gz file which I am converting to base64 using the following method:
base64_logs=$(base64 logs.tar.gz)
I am using following curl command:
content_response=$(curl -v \
-X PUT \
-u some-user:$(params.git-token) \
-H "Accept: application/vnd.github.v3+json" \
$content_url \
-d '{"message": "some message", "content": "'"$base64_logs"'"}')
The error message I get is
{ "message": "Problems parsing JSON", "documentation_url": "https://docs.github.com/enterprise/2.22/rest/reference/repos#create-or-update-file-contents" } 400
I am not sure where I am getting this wrong. I tried to use a hardcoded base64 string, and it worked.

Solved.
Needed extra whitespace.
base64_logs=$(base64 logs.tar.gz | tr -d \\n)
or you may need to use \\r depending on your OS. See below-related answer for more info.

Ambari cluster + what is the right syntax in order to upload blueprint json file to ambari cluster

we have Ambari cluster Version 2.5.0.3 , while all clients machines are Linux redhat
first I generated the json file to my Linux machine as the following: ( on ambari server machine )
curl -H "X-Requested-By: ambari" -X GET -u admin:admin http://130.14.6.28:8080/api/v1/clusters/HDP01\?format\=blueprint > blueprint.json
then I update the blueprint.json file with some changes about the parameters and their values
finally my target is to upload the new blueprint.json to ambari cluster in order to take affect !
path=/root
curl -H "X-Requested-By: ambari" --data # -X POST -u admin:admin http://130.14.6.28:8080/api/v1/blueprints/HDP01 -d #$path/blueprint.json
but I get the following errors ( seems because wrong syntax )
Warning: Couldn't read data from file "", this makes an empty POST. {
"status" : 400, "message" : "Invalid Request: Malformed Request Body. An
exception occurred parsing the request body: Unexpected character ('&'
(code 38)): expected a valid value (number, String, array, object, 'true',
'false' or 'null')\n at [Source: java.io.StringReader#4a3484a6; line: 1,
column: 3]"
please advice what is wrong in my syntax ?
And what is the right syntax in order to upload the new update blueprint.json file

Did you try to validate your JSON online e.g. at https://jsonformatter.curiousconcept.com/ ?
Looks like the problem is with general JSON syntax

In curl command used to upload new bloueprint.json, you are using --data # as well as -d #$path/blueprint.json. -d and --data are used for same purpose hence first occurance i.e. --data # takes effect and command tried to locate file with no path i.e. "".
You may remove --data # to fix Couldn't read data from file "" error.

Error "invalid json" in inserting document in Couchdb through command line

I am getting any "error: bad request,invalid json" while running
curl -X PUT "http://localhost:5984/test" -d '{"valid":"json"}'
what to do for inserting document in database test through command line???

When doing a PUT the _id of the document should be provided in the URL. So e.g.:
curl -X PUT "http://localhost:5984/test/my-id" -d '{"valid":"json"}'
If you want Couch to generate the id, use a POST instead.

CouchDB cURL Windows Command Line Invalid JSON

Running the following command from a Windows command line using cURL attempting to post a new document to an existing CouchDB database (named test) fails:
curl -H "Content-Type: application/json" -X POST "http://127.0.0.1:5984/test" -d {"valid":"json"}
It returns the error:
{"error":"bad_request","reason":"invalid_json"}
The JSON is valid so what gives?

The answer is related to the formatting of the JSON string on the command line. Even though it is proper JSON when you type it, the command line, it seems, must reformat it before sending it.(Maybe someone else can explain why it does this in more detail.) To fix this you need to escape your quotations in the command line like so:
curl -H "Content-Type: application/json" -X POST "http://127.0.0.1:5984/test" -d {"""valid""":"""json"""}
See the extra quotation marks? This should work and return "ok:true" with an id and revision number.

You have to quote also the whole statement to support spaces like: -d "{\"title\":\"There is Nothing Left to Lose\" , \"artist\":\"Foo Fighters\"}"

Import/Index a JSON file into Elasticsearch

I am new to Elasticsearch and have been entering data manually up until this point. For example I've done something like this:
$ curl -XPUT 'http://localhost:9200/twitter/tweet/1' -d '{
"user" : "kimchy",
"post_date" : "2009-11-15T14:12:12",
"message" : "trying out Elastic Search"
}'
I now have a .json file and I want to index this into Elasticsearch. I've tried something like this too, but no success:
curl -XPOST 'http://jfblouvmlxecs01:9200/test/test/1' -d lane.json
How do I import a .json file? Are there steps I need to take first to ensure the mapping is correct?

The right command if you want to use a file with curl is this:
curl -XPOST 'http://jfblouvmlxecs01:9200/test/_doc/1' -d #lane.json
Elasticsearch is schemaless, therefore you don't necessarily need a mapping. If you send the json as it is and you use the default mapping, every field will be indexed and analyzed using the standard analyzer.
If you want to interact with Elasticsearch through the command line, you may want to have a look at the elasticshell which should be a little bit handier than curl.
2019-07-10: Should be noted that custom mapping types is deprecated and should not be used. I updated the type in the url above to make it easier to see which was the index and which was the type as having both named "test" was confusing.

Per the current docs, https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html:
If you’re providing text file input to curl, you must use the
--data-binary flag instead of plain -d. The latter doesn’t preserve newlines.
Example:
$ curl -s -XPOST localhost:9200/_bulk --data-binary #requests

We made a little tool for this type of thing https://github.com/taskrabbit/elasticsearch-dump

One thing I've not seen anyone mention: the JSON file must have one line specifying the index the next line belongs to, for every line of the "pure" JSON file.
I.E.
{"index":{"_index":"shakespeare","_type":"act","_id":0}}
{"line_id":1,"play_name":"Henry IV","speech_number":"","line_number":"","speaker":"","text_entry":"ACT I"}
Without that, nothing works, and it won't tell you why

I'm the author of elasticsearch_loader
I wrote ESL for this exact problem.
You can download it with pip:
pip install elasticsearch-loader
And then you will be able to load json files into elasticsearch by issuing:
elasticsearch_loader --index incidents --type incident json file1.json file2.json

I just made sure that I am in the same directory as the json file and then simply ran this
curl -s -H "Content-Type: application/json" -XPOST localhost:9200/product/default/_bulk?pretty --data-binary #product.json
So if you too make sure you are at the same directory and run it this way.
Note: product/default/ in the command is something specific to my environment. you can omit it or replace it with whatever is relevant to you.

Adding to KenH's answer
$ curl -s -XPOST localhost:9200/_bulk --data-binary #requests
You can replace #requests with #complete_path_to_json_file
Note: #is important before the file path

just get postman from https://www.getpostman.com/docs/environments give it the file location with /test/test/1/_bulk?pretty command.

You are using
$ curl -s -XPOST localhost:9200/_bulk --data-binary #requests
If 'requests' is a json file then you have to change this to
$ curl -s -XPOST localhost:9200/_bulk --data-binary #requests.json
Now before this, if your json file is not indexed, you have to insert an index line before each line inside the json file. You can do this with JQ. Refer below link:
http://kevinmarsh.com/2014/10/23/using-jq-to-import-json-into-elasticsearch.html
Go to elasticsearch tutorials (example the shakespeare tutorial) and download the json file sample used and have a look at it. In front of each json object (each individual line) there is an index line. This is what you are looking for after using the jq command. This format is mandatory to use the bulk API, plain json files wont work.

As of Elasticsearch 7.7, you have to specify the content type also:
curl -s -H "Content-Type: application/json" -XPOST localhost:9200/_bulk --data-binary #<absolute path to JSON file>

I wrote some code to expose the Elasticsearch API via a Filesystem API.
It is good idea for clear export/import of data for example.
I created prototype elasticdriver. It is based on FUSE

If you are using the elastic search 7.7 or above version then follow below command.
curl -H "Content-Type: application/json" -XPOST "localhost:9200/bank/_bulk? pretty&refresh" --data-binary #"/Users/waseem.khan/waseem/elastic/account.json"
On above file path is /Users/waseem.khan/waseem/elastic/account.json.
If you are using elastic search 6.x version then you can use the below command.
curl -X POST localhost:9200/bank/_bulk?pretty&refresh --data-binary #"/Users/waseem.khan/waseem/elastic/account.json" -H 'Content-Type: application/json'
Note: Make sure in your .json file at the end you will add the one empty
line otherwise you will be getting below exception.
"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]"
},
`enter code here`"status" : 400

if you are using VirtualBox and UBUNTU in it or you are simply using UBUNTU then it can be useful
wget https://github.com/andrewvc/ee-datasets/archive/master.zip
sudo apt-get install unzip (only if unzip module is not installed)
unzip master.zip
cd ee-datasets
java -jar elastic-loader.jar http://localhost:9200 datasets/movie_db.eloader

If you want to import a json file into Elasticsearch and create an index, use this Python script.
import json
from elasticsearch import Elasticsearch
es = Elasticsearch([{'host': 'localhost', 'port': 9200}])
i = 0
with open('el_dharan.json') as raw_data:
json_docs = json.load(raw_data)
for json_doc in json_docs:
i = i + 1
es.index(index='ind_dharan', doc_type='doc_dharan', id=i, body=json.dumps(json_doc))
