Hi, i have nested objects in my json like this
{ assetClass: 'HG', security: {fullName: 'foo', identifiers: { USERID: '123' } } }
But i can not access the nested objects. So i found a solution which have 15 reps.
I use it like this

Normally it works great i can access the nested objects.
But when i try to group my columns (in this case Full Name column) result is undefined.

What do you suggest ?
