Parsing bug with array containing empty object

[Chris Virgona]

I'm using "Unflatten From JSON String" with no type input wired.

The following JSON string causes a parsing error:
{"arr1": [
{ "key1": 1, "key2": {} }
]}

The trigger for the error seems to be the empty object under "key2".

Interestingly when "key1" is removed the empty object no longer triggers an error:
{"arr1": [
{ "key2": {} }
]}

Thanks for the excellent JSON tool by the way. This is the first parsing error I have observed after many years of use!
