GraphQL cursor error with pagination

Trying to pull multiple variants for a given product, when supplying the cursor, the results are the same, and if we loop through this creates an endless loop.

example query and response when running manually in postman

{ 
	product (id: "gid://shopify/Product/6691885514921") {
		id
		variants (first: 2) {
			pageInfo {
				hasNextPage
			}
			edges {
				cursor
				node {
					id
					sku
				}
			}
		}
	}
}
