Hi Guys !

I have a document which contains an array of JSONObject.

When I add a JSONObject in my array from Sense like this, it works fine :

[quote] POST index/type/1/\_update  
{  
"script" : {  
"inline": "ctx.\_source.people.add(params.person)",  
"lang": "painless",  
"params" : {  
"person" : {  
"field" : "test"  
}  
}  
}  
}  
[/quote]

But when I'm trying to add throw the Java Api with this code :

> [@](#):
>
> Map\<String, Object\> params = new HashMap\<\>();  
> params.put("person", valueTest);  
> Script scriptTest = new Script(ScriptType.INLINE, "painless", "ctx.\_source.people.add(params.person);", params);  
> UpdateRequest bulkRequest = new UpdateRequest("index","type",id)  
> .script(scriptTest);  
> client.prepareUpdate("cityflow9","traject",id).setScript(scriptTest).execute().get();

I got the following error : java.io.IOException: can not write type [class org.json.JSONObject]

I tried to replace the JSONObject with a XContentBuilder but the same exception is throwing...

Can anyone has an explenation or an idea how I can fix this ?

Can you show the code snippet that creates `valueTest`?

Hello,

Thanks for replying !

Yes, of course, I try this :

> [@](#):
>
> ```
> JSONObject valueTest = new JSONObject();
> valueTest.put("macAdresse", "Testing");
> valueTest.put("duration", 123);
> 
> ```

And I try this as well :

> [@](#):
>
> XContentBuilder valuetest = jsonBuilder()  
> .startObject()  
> .field("macAdresse", "Testing")  
> .field("duration", 123)  
> .endObject();

Both give me the error ☹

Try with a `HashMap`
