Nested Result Objects ParentNode not working

Hello,

I am using the restsql adapter for alloy sync. I've nested object & am not able to parse it using the parentNode method as specified. I've attached the sample output . From that I need the contents of appsettings but specifing

parentNode : appsettings

OR

parentNode : response.appsettings

is not working.

Any help is appreciated.

Thanks,
