Need to parse Json buckets

[carucha]

Hi... I have this Item that GET a JSONextracted from my elasticsearch DB.

I made a discovery rule, with this JSON as dependent item.


What i need to extract is the key and doc_count of each bucket, but i don't know how to express the "changing field"

I need all of them...:
$.aggregations.2.buckets.[1].key
$.aggregations.2.buckets.[2].key
$.aggregations.2.buckets.[3].key
and so on....

How do i put on a LLD macro, that i want

$.aggregations.2.buckets.["1 to n"].key ??

I hope u can understand

Here is my Json
