Dear all,  
the following body posted to [http://localhost:9200/products/\_bulk](http://localhost:9200/products/_bulk) with appropriate content type  
{ "products": ["apple", "dog", "puppy"],"user": "Sophia" }  
{ "products": ["puppy","bicicle"], "user": "Jan" }  
{ "products": ["apple","puppy"], "user" : "Ethan" }

is delivering

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

```

However, the following body posted to [http://localhost:9200/products/\_doc/1](http://localhost:9200/products/_doc/1)  
{  
"products" : ["apple","dog","puppy"],  
"user" : "Sophia"  
}

works properly.

Can you please help ?  
Thankyou

Sounds like you are not following the bulk format. Have a look at [https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html)

Before each document, you need a metadata line as shown in [the docs for the bulk API](https://www.elastic.co/guide/en/elasticsearch/reference/7.2/docs-bulk.html). So your example would be something like:

```auto
POST products/_bulk
{ "index" : {"_id" : "1" } }
{ "products": ["apple", "dog", "puppy"],"user": "Sophia" }
{ "index" : {"_id" : "2" } }
{ "products": ["puppy","bicicle"], "user": "Jan" }
{ "index" : {"_id" : "3" } }
{ "products": ["apple","puppy"], "user" : "Ethan" }

```

(providing IDs is optional, if you don't provide one, Elasticsearch will auto-generate one)

Edit: Beaten! Sorry for the double post.
