I am trying to add new object to list of object in an elastic search index with java HighLevelRestClient. I know I can do it with following query:
```auto
String query = "ctx._source.custom_analysis.custom_analysis_list.add(params.custom_properties)";
```
This script adds a new value to the list but does not create object in index named 'custom\_properties'
But I want the output similar to following where in a new field name (custom\_properties ) is added as well is added to the index while I add a new object to arraylist.
```auto
"custom_analysis" : {
"custom_analysis_list" : [
{
"custom_properties" : {
"deleted" : true,
"name" : "Custom Analysis1",
"description" : "Custom analysis for yogurt ",
"last_modified_date" : "01-08-2020",
"id" : "1",
"creation_date" : "01-08-2020",
"show_on_screen" : false,
"type" : "yogurt_us"
}
},
{
"custom_properties" : {
"deleted" : false,
"name" : "Custom Analysis2",
"description" : "Custom analysis description ",
"last_modified_date" : "01-01-2020",
"id" : "2",
"creation_date" : "01-01-2020",
"show_on_screen" : false,
"type" : "yogurt_us"
}
}]
}
```
