Description

If i have the following record:

{
  "queue": {
     "count": 1,
     "size": "1 MB"
  }
}

And I want to get rid of the 'queue' element I should be able to do so by using UpdateRecord with a property name of "/" and a value of "/queue/*"

Currently, if I try this, though, I get an error indicating that more than 1 element has been selected. We should instead just create a 'record' object with both the 'count' and 'size' fields and set that as the root so that the result is:

{
  "count": 1,
  "size": "1 MB"
}
