> Key: NIFI-4306
> URL: https://issues.apache.org/jira/browse/NIFI-4306
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Reporter: Mark Payne

>
> If i have the following record:
> {code}
> {
> "queue": {
> "count": 1,
> "size": "1 MB"
> }
> }
> {code}
> 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:
> {code}
> {
> "count": 1,
> "size": "1 MB"
> }
> {code}
