Following is my document structure

```auto
"ListOfResourcesForTheTeam”:[{"Resource":{"Name": "XYZ", "Phone": 31213}}, { "Resource":{"Name": "ABC", "Phone": 4365}}]

```

Using update\_by\_query using painless scripting I am trying to update the phone number of the second resource as following:

docFieldPath = ListOfResourcesForTheTeam.1.Resource

```auto
ctx._source.docFieldPath.putAll(content)

```

The script errors out as it tries to find “docFieldPath”.

But the following works:

```auto
ctx['_source'][firstPartOfDocFieldPath][secondPartOfDocFieldPathAsInteger][thirdPartOfDocFieldPath].putAll(content);

```

Is there a way in painless script such that I can directly use docFieldPath instead of tokenising it.
