Steps to reproduce:

1. Create an item with vmware.vm.snapshot.get[] key for a VM with no active snapshots

Result:

The returned JSON data is missing information for: oldestdate, oldestage }}and{{ latestage attributes.

{{

{"snapshot":[],"count":0,"latestdate":null,"size":0,"uniquesize":0}

}}

JSONPath preprocessing fails (see screenshot)
**

Expected:

According to documentation, if no snapshot exists, the following JSON data should be returned:

{{

{ "snapshot": [], "count": 0, "latestdate": null, "latestage": 0, "oldestdate": null, "oldestage": 0, "size": 0, "uniquesize": 0}

}}
