Unable to loop through my postman response - arrays

Question

I have this json respone from postman
I want to write a test to return failure if key "value" in the array is < 50.
It would loop through the array once the condition is not met it fails
I have tried this
pm.test('Matches value', () => {
_.each(pm.response.json(), (arrItem) => {
if (arrItem.persID === 'personID_2') {
throw new Error(`Array contains ${arrItem.persID}`)
}
})
});
My response
{
"groups": [
{
"title": "Maids",
"subTitle": null,
"description": null,
"featured": false,
"items": [
{
"id": "1",
"title": "AA",
"subTitle": "AA",
"thumbnail": "AA",
"priceStartingAt": {
"value": 50,
"baseCurrency": "USD",
"exchangeEnabled": true,
"exchangeRates": {
"aed": 3.672973
}
},
"categories": [
"Activity"
]
},
{
"id": "2",
"title": "BB",
"subTitle": "BB",
"thumbnail": "BB",
"priceStartingAt": {
"value": 20.01,
"baseCurrency": "USD",
"exchangeEnabled": true,
"exchangeRates": {
"aed": 3.672973
}
},
"categories": [
"Activity"
]
}
]
}
]
In this case the test should fail because the value in the second array is 20.01

I'm not sure where you copied that code from but it was never going to work as all the references relate to a different response body.
To keep the same convention and have the throw new Error in there you could do this:
pm.test('Value is not below 50', () => {
_.each(pm.response.json().groups[0].items, (arrItem) => {
if (arrItem.priceStartingAt.value < 50) {
throw new Error(`Array contains ${arrItem.priceStartingAt.value}`)
}
})
});
Or you could just check if the items are not below 50 like this.
pm.test('Value is not below 50', () => {
_.each(pm.response.json().groups[0].items, (arrItem) => {
pm.expect(arrItem.priceStartingAt.value).to.not.be.below(50)
})
});
