*How I found the problem*:


*I've already tried*:
I've tried this code but the result is an array of undefined
like this:
[undefined, undefined, undefined, undefined, undefined, …]

var response = pm.response.json();

var dataIds = Object.values(response).map(dataId => data.id);

console.log(dataIds);

Hello @xakrurychle,

you can use below code

var response = pm.response.json()
var dataIds = response.data
dataIds.forEach(element => console.log(element.id));

cheers
