How to validate Array object attribute if present in Karate

Question

What would be the proper way to create the match string in the case below?

I am stuck with the correct match string which would validate both of the below JSON(s).

In one of them, we have the "Periods" data,

{
    "id": 1,
    "period":
    [
        {
            "startDate": "2022-05-05",
            "endDate": "2022-05-06"
        },
        {
            "startDate": "2022-06-05",
            "endDate": "2022-06-06"
        }
    ]
}

on the other its a null array.

{
    "id": 1,
    "period": []
}

I have been trying with the below match string but the same seems to fail

* match response contains deep "##({period: [{startDate: '#notnull'}]})"

Here you go:

* def dateSchema = { startDate: '#string', endDate: '#string' }
* match response == { id: '#number', period: '#[] dateSchema' }

Thank you @peter. This worked marvelously. made a minor change to match * match response == { id: '#number', period: '##[] dateSchema' } to cater the scenario if the key is not sent. Thank you.
