When I get an object, I want to get an array of objects that's on the object

const set = await SetsController.getSet(setID);

const setName = set.name;
const setId = set._id.toString();

console.log(setId);
console.log(set.cards);

set contains an array called cards.

When I do this:

console.log(set);

The whole set object prints, including the cards array. However, when I do this:

console.log(set.cards);

it prints undefined

What am I doing wrong?
