I have request, that works in Kibana console:

> POST test\_idx1/\_update/1  
> {  
> "script" : "ctx.\_source.remove('field1')"  
> }

I copied it as cURL:

> curl -XPOST "[http://localhost:9200/test\_idx1/\_update/1](http://localhost:9200/test_idx1/_update/1)" -H 'Content-Type: application/json' -d'{ "script" : "ctx.\_source.remove("field1")"}'

From which I tried to do deduct HTTP filter:

> filter {  
> http {  
> url =\> "[http://localhost:9200/test\_idx1/\_update/1](http://localhost:9200/test_idx1/_update/1)"  
> verb =\> "POST"  
> user =\> "logstash\_user"  
> password =\> "logstash\_user\_password"  
> body\_format =\> "json"  
> body =\> "{\"script\" : \"ctx.\_source.remove(\\\"field1\\\")\"}"  
> }  
> }

After running Logstash no error is logged, even on DEBUG level. No update is happening in Elasticsearch.  
What am I missing?
