How to check object exists in an array

[dd_snaplogic]

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

Now I’m accessing each element of group in mapper and I require to have the null-safe access check enabled.

Now if I’m trying to check whether the group array have object in 7th position ie jsonPath($, “$group[6].rowKey[0]”) but, i’m getting null as a response

I’ve tried using various ways (eg. sl.ensureArray(jsonPath($, “$group[6]”))) but it seems when null-safe access check is enabled nothing works
What is the way to check whether the element or object exists?

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

[Abhishek_Soni37 · Accepted solution]

dd_snaplogic:

$.hasPath($group[6])

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.
