productSet does not return variants

I am running productSet in bulk, and I want it to return the variants. However, it returns an empty array. Here is the query that I’m sending:

return <<

And I am getting the following:

```javascript
{
  "data": {
    "productSet": {
      "product": {
        "id": "gid://shopify/Product/10025039823153",
        "handle": "someHandle",
        "status": "DRAFT",
        "options": [
          {
            "id": "gid://shopify/ProductOption/12626381799729",
            "name": "sizes",
            "optionValues": [
              {
                "id": "gid://shopify/ProductOptionValue/4632684986673",
                "name": "36-37"
              },
              {
                "id": "gid://shopify/ProductOptionValue/4632685019441",
                "name": "38-39"
              },
              {
                "id": "gid://shopify/ProductOptionValue/4632685052209",
                "name": "40-41"
              },
              {
                "id": "gid://shopify/ProductOptionValue/4632685084977",
                "name": "42-43"
              }
            ]
          }
        ],
        "variantsCount": {
          "count": 4
        },
        "variants": {
          "edges": []
        }
      },
      "productSetOperation": null,
      "userErrors": []
    }
  },
  "__lineNumber": 58
}

Is there any detail that I am missing? The above should work I believe
