Images for products with over 100 variants

I am trying to create a product with more than 100 variants with the productSet mutation in asynchronous mode, but getting an error VARIANTS_OVER_LIMIT. Is this not available yet ? I am trying on a development store.
Below is the mutation (I am providing False for synchronous, and version is 2024-04)

mutation createProductAsynchronous($productSet: ProductSetInput!, $synchronous: Boolean!) {
  productSet(synchronous: $synchronous, input: $productSet) {
    product {
      id
    }
    productSetOperation {
      id
      status
      userErrors {
        code
        field
        message
      }
    }
    userErrors {
      code
      field
      message
    }
  }
}

You should NOT be seeing the error “VARIANTS_OVER_LIMIT” if you have set up the development store with the “Extended Variants” Developer preview.

Can you make sure you are setting up a development store using the following steps:

  1. Go to partners.shopify.com
  2. Click on Stores in the left navigation panel
  3. Click on Add Store → Create Development store
  4. Select “Create a store to Test and Build”
  5. Select Developer preview
  6. From the drop down select “Extended Variants”
