Shopify GraphQL: How to add variants using Python and GraphQL

Question

I've been trying to create product with variants using Python and GQL,

but lacking something and dosen't work as I want.

it says "Field 'optionValues' doesn't exist on type 'ProductOption'" but I reffer to a official document and copy it

https://shopify.dev/docs/api/admin-graphql/2023-10/mutations/productcreate#examples-Create_a_product_with_options_and_option_values

import requests
import json

# Shopify API credentials
shop_url = "ShopURL"
access_token = "access_token"

# GraphQL endpoint
graphql_url = f"{shop_url}/admin/api/2023-10/graphql.json"

# Build the GraphQL mutation to create a product with options and option values
mutation = """
mutation CreateProductWithOptions($input: ProductInput!) {
  productCreate(input: $input) {
    userErrors {
      field
      message
    }
    product {
      id
      options {
        id

The way you're able to use options to create variants is like this:

mutation CreateProductWithOptions($input: ProductInput!) {
  productCreate(input: $input) {
    product {
      id
      options {
        name
        values
        id
        position
      }
      variants(first: 5) {
        nodes {
          id
          title
          selectedOptions {
            name
            value
          }
        }
      }
    }
    userErrors {
      message
      field
    }
  }
}

{
  "input": {
    "options": ["Size", "Color"],
    "title": "New Product",
    "variants": [
      {
        "options": ["Small", "Red"]
      },
      {
        "options": ["Small", "Green"]
      },
      {
        "options": ["Medium", "Green"]
      },
      {
        "options": ["Medium", "Red"]
      }
    ]
  }
}
