Hi,

I'm trying to rename data that is in this shape:  
 ![rename](https://us1.discourse-cdn.com/elastic/original/3X/6/4/644db79f0576b776b964488256c7310a09507bcc.png)

using this:

```auto
POST r_xair_signals-2020-06/_update/2020-06-15T22:23:00Z_-1344027716
{
  "doc" : {
        "Customer ImpactedNested" : "CustomerImpactedNested"
    }
}

```

But I'm getting:

```auto
"type": "mapper_parsing_exception",
    "reason": "object mapping for [Customer ImpactedNested] tried to parse field [Customer ImpactedNested] as object, but found a concrete value"

```

Any ideas?

Thanks!
