Graph QL mutation 'productVariantsBulkCreate' strategy broken

[HelloToxicity]

Hey,

I was working with creating a product with variants which had unique prices and inventory quantities and found that the 'REMOVE_STANDALONE_VARIANT' wasn't working. When I try to request productVariantsBulkCreate using that param, I am hit with the error:

      "userErrors": [
        {
          "field": ["variants", "0"],
          "message": "The variant '11 / 2323' already exists. Please change at least one option value."
        }
      ]

Don;t mind the weird option names, they were typed in haste. 
The 11/ 2323 variant is created when I add options to the product in my 'productOptionsCreate' which returns this as the variant.

        "variants": {
          "nodes": [
            {
              "id": "gid://shopify/ProductVariant/49370552041756",
              "title": "11 / 2323",
              "selectedOptions": [
                { "name": "test", "value": "11" },
                { "name": "test_2", "value": "2323" }
              ]
            }
          ]
        },

I believe this is an bug, but just in case I will include my full query:

{
  "query": "mutation productVariantsBulkCreate($productId: ID!, $variantsInput: [ProductVariantsBulkInput!]!) {\n  productVariantsBulkCreate(productId: $productId, variants: $variantsInput) {\n    product {\n      id\n    }\n    productVariants {\n      id\n      metafields(first: 1) {\n        edges {\n          node {\n            namespace\n            key\n            value\n          }\n        }\n      }\n    }\n    userErrors {\n      field\n      message\n    }\n  }\n}",
  "variables": {
    "productId": "gid://shopify/Product/9530321109276",
    "strategy": "REMOVE_STANDALONE_VARIANT",
    "variantsInput": [
      {
        "price": 2323,
        "inventoryQuantities": [
          {
            "availableQuantity": 23,
            "locationId": "gid://shopify/Location/98154283292"
          }
        ],
        "optionValues": [
          { "name": "11", "optionName": "test" },
          { "name": "2323", "optionName": "test_2" }
        ]
      },
      {
        "price": 3,
        "inventoryQuantities": [
          {
            "availableQuantity": 43,
            "locationId": "gid://shopify/Location/98154283292"
          }
        ],
        "optionValues": [
          { "name": "11", "optionName": "test" },
          { "name": "232", "optionName": "test_2" }
        ]
      }
    ]
  }
}

Thanks for all the help!

Found out I was being silly - for anyone stumbling across this in the future the solution is adding the ProductVariantsBulkCreateStrategy  variable to the GQL request.
