I am trying to reindex an index and trying to create new field from two object fields.  
I am not able to access the field value latitude and it is returning null.

code below  
POST \_reindex  
{  
"source": {  
"index": "append7"  
},  
"dest": {  
"index": "append8"  
},  
"script": {  
"source": "ctx.\_source['NEW'] = ctx.\_source['a.b.latitude'] + ',' + ctx.\_source['a.b.longitude]",  
"lang": "painless"  
}  
}

My \_source shows like this:  
"a":{  
"b":{  
"latitude":"42.00",  
"longitude":"74.32"  
}

}

I am using elastic search 6.3.1 .  
I was able to access the field using the below method but don't know why ". " operatror not working on inner object fields.

```
"script": {
"source": """ctx._source['location_config'] = ctx._source.a.get('Response._latitude')+ ',' + ctx._source.a.get('Response._longitude')""",

"lang": "painless"
}`Preformatted text`
```
