I use ElasticsearchOperations  
directories its the List Directory

```
String scriptText = "if (ctx._source.businessPartnerParams != null) { " +
    "ctx._source.businessPartnerParams.bpName = 'test 3 ' " +
    "}";
HashMap<String, Object> params = new HashMap<>();

params.put("directories", directories);
UpdateQuery updateQuery = UpdateQuery.builder(Query.findAll())
    .withScriptType(INLINE)
    .withLang("painless")
    .withScript(scriptText)
    .withParams(params)
    .build();
ByQueryResponse byQueryResponse = operations.updateByQuery(updateQuery,
    IndexCoordinates.of(RELEVANT_INDEX_NAME));

```

and in kibana its view

POST /partners-rd-partners-partners-1/\_update\_by\_query?refresh=false  
{  
"query": {  
"wrapper": {  
"query": "eyJtYXRjaF9hbGwiOnt9fQ=="  
}  
},  
"script": {  
"params": {  
"directories": "[Directory(id=DirectedTypeBUR001, code=BUR001, description=Имеет контактное лицо, type=DirectedType, value=null), Directory(id=DirectedTypeBUR002, code=BUR002, description=Имеет контактного партнера, type=DirectedType, value=null), Directory(id=DirectedTypeBUR003, code=BUR003, description=Имеет члена жилищного объединения, type=DirectedType, value=null)]"  
},  
"lang": "painless",  
"source": """def message = params.directories.toArray();  
Debug.explain(message);  
if (ctx.\_source.businessPartnerParams != null) {  
ctx.\_source.businessPartnerParams.bpName = 'test 3 '  
}"""  
}  
}

I dont get param - its string not List. How put params List?
