Elastic search Update by Query to Update Complex Document - elasticsearch

Question

I have a use case of elastic search to update a doc.
My doc is something like this-
{
"first_name" : "firstName",
"last_name" : "lastName",
"version" : 1234,
"user_roles" : {
"version" : 12345,
"id" : 1234,
"name" : "role1"},
},
"groups" : {
"version" : 123,
"list": [
{"id":123, "name" : "ashd"},
{"id":1234, "name" : "awshd"},
]
}
}
Now depepeding on some feed I will either will be updating the parent doc or will be updating the nested doc.
I am able to find how to update the basic attributes like firstName and lastName but unable to get how to update complex/nested ones
I did something like from REST client-
"script": {
"inline": "ctx._source.user_roles = { "id" : 5678, "name" :"hcsdl"}
}
but its giving me exception-
Actual use case-
I will actually be getting a Map in java.
This key can be simple key like "first_name" or can be complex key like "user_role" and "groups"
I want to update the document using update by query on version.
The code I wrote is something like-
for (String key : document.keySet()) {
String value = defaultObjectMapper.writeValueAsString(document.get(key));
scriptBuilder.append("ctx._source.");
scriptBuilder.append(key);
scriptBuilder.append('=');
scriptBuilder.append(value);
scriptBuilder.append(";");
}
where document is the Map
Now I might get the simple fields to update or complex object.
I tried giving keys like user_roles.id and user_roles.name and also tried giving complete user_roles but nothing is working.
Can someone helpout

Try this with groovy maps instead of verbatim JSON inside your script:
"script": {
"inline": "ctx._source.user_roles = [ 'id' : 5678, 'name' : 'hcsdl']}
}
