GraphQl schema for object in object?

Question

JavaScript

Hey!
There is such data in .json

{
  "goods": [
    {
      "name": "LeBron XVI Hot Lava White",
      "price": 100,
      "sizes": {
        "39": true,
        "40": false,
        "41": true,
        "42": true,
        "43": true
      }
    }
  ]
}

These are the resolvers

const DATA = require("./fakeData/data");

const mapGood = (good, id) => good && { id, ...good };

const resolvers = {
  goods: () => DATA.goods.map(mapGood),
  good: ({ id }) => mapGood(DATA.goods[id], id),
};

I make a query like this in GraphQl and I get the error How do I output the sizes

object in this case?
