Also, for the below screesnshot, i want to take the index as to how many responses returned. Since this is at the root level i tried $.map(value => value.extend({‘Batch_Index’:$.indexOf(value)})), but it is giving me an an error as
“Map type does not have a method named: map, found in: …dexOf(value)})). Perhaps you meant: mapKeys, mapValues”"
