the demo document:  
`curl -XPUT http://localhost:9200/blog/article/1 -d '{"title": "New version of Elasticsearch released!", "content": "Version 1.0 released today!", "tags": ["announce","elasticsearch", "release"]}'`

then i want add a field:  
`curl -XPOST http://localhost:9200/blog/article/1/_update -d '{"script": "ctx._source.counter += 1","upsert": {"counter" : 0}}'`

I get the msg:

{  
"error": {  
"root\_cause": [  
{  
"type": "remote\_transport\_exception",  
"reason": "[Delphine Courtney][127.0.0.1:9300][indices:data/write/update[s]]"  
}  
],  
"type": "illegal\_argument\_exception",  
"reason": "failed to execute script",  
"caused\_by": {

"reason": "failed to run inline script [ctx.\_source.counter += 1] using lang [groovy]",

"type": "null\_pointer\_exception",  
"reason": "Cannot execute null+1"  
}  
}  
},  
"status": 400  
}

my config file content:  
`script.inline: on script.indexed: on script.engine.groovy.inline.aggs: on script.engine.groovy.inline.update: on`

i'm a newcomer.  
thank you.

You did not set any value for counter in the original document. How could it be incremented?

I resolved，  
ctx.\_source.counter += 1  
==》ctx.\_source.counter = 1

thank you!

</div>

But why do you want to use a script for such an update?

Ok.

Just to make sure you understand, if you want to send a new version of a document (update a document that is), you can do:

```auto
# This is the first version of the doc
PUT index/type/1
{
  "foo": "bar"
}

# This is the new version of the doc
PUT index/type/1
{
  "foo": "baz"
}

```

You don't need to run a script for that.
