Hi, I've a stored script :

```auto
POST _scripts/1_jd_job_domain
{
  "script": {
	"lang": "painless",
	"params": {
	  "generic_domain": "generic domain"
          [...]
	},
	"source" : """if ( ctx._source.car?.current_assignment?.job_description?.jdl1_id_reports_to != null && ctx._source.car?.current_assignment?.job_description?.jdl3_id_reports_to != null)  
                     { Map map_generic_details = new HashMap()
		     ; ArrayList list_domain_list = new ArrayList()
		     ; map_generic_details.put('index type' , params.generic_domain)
	   	    ;map_generic_details.put('value',params.generic_plus_specific_plus_intermediate)
                    [...]

```

I call this script from logstash output plugin. It works fine for the rest except it doesn't retrieve the values from the params. What am I doing wrong ?

I've also tried defining those params in the logstsh output part like this :  
parameters =\> {"generic\_domain" =\> "generic\_domain"}

but then I've the error:  
Response code '400' contacting Elasticsearch at URL '[http://localhost:9200/?generic\_domain=generic\_domain](http://localhost:9200/?generic_domain=generic_domain)'"}

What am I doing wrong? I would prefer a solution where I could get the parameters values from the stored script if possible. Thank you

</div>

On the logstash output I've tried :

```auto
parameters => { "event" => {"taxless_total_price" => "90"}}
But now it shows the error : Pipeline aborted due to error {:pipeline_id=>"main", :exception=>java.net.URISyntaxException: Illegal character in query at index 54: http://elastic:secret4hrsearch@localhost:9200/?event=["taxless_total_price", "90"]

```

could you help please, tanks.

I think the `parameters` option should just be `{ "key1" => "value1" "key2" => "value2" }`. Otherwise the [flat\_map](https://github.com/logstash-plugins/logstash-output-elasticsearch/blob/fe0a24135a6f18f64415a116f09bc5418b83f15e/lib/logstash/outputs/elasticsearch/http_client.rb#L381) call will create an array which needs to be encoded.
