    "id": 33,
    "name": "category1"
  },

    "id": 34,
    "name": "category2"
  }

[
  {
    "id": 1201,
    "name": "product1",
    "categories": [
      {
        "id": 33,

      }
    ]
  }
]

on running this query

{
  products(filter: {category_id: {in: ["33", "34"]}}) {
    total_count
    items {
      id
      name
      categories {
