How to check object exists in an array

I have an array eg { “groupBy”: { “rowKey”: “0141116963814” }, “group”: [ { “rowKey”: “0141116963814” }, { “rowKey”: “0141116963814” }, { “rowKey”: “0141116963814” } ] ...

    You need to put $group[6], inside quotes like $.hasPath(“$group[6]”), if there is no item at index 6 in the group array, this expression will return false.

You can use the below expression to see if the element is an object or not.

typeof(input)

On the other hand, if you want to check if a specific element/path exist or not, use below. Docs

$.hasPath(“$putThePath”)

Let us know if it helps.

No when an element doesn’t exists and the null-safe option is enabled it is giving me null as a value no matter what condition I’m passing.

ie typeof($group[6]) will return null as well $.hasPath($group[6]) will return null
