Error when querying the slug of deleted products

[BenVuti]

I'm trying to find the slug of all the products that a customer bought with this query:

query {
  activeCustomer {
    orders(
      options: {
        filter: {
          state: { in: ["PaymentAuthorized", "PaymentSettled", "Delivered"] }
          totalQuantity: { gt: 0 }
        }
      }
    ) {
      items {
        lines {
          productVariant {
            product {
              slug
            }
          }
        }
      }
    }
  }
}

During my testing I deleted a product previously bought by the customer.
This result in the following error when running the query :

{
  "errors": [
    {
      "message": "No Product with the id '16' could be found",
      "locations": [
        {
          "line": 9,
          "column": 13
        }
      ],
      "path": [
        "activeCustomer",
        "orders",
        "items",
        16,
        "lines",
        0,
        "productVariant",
        "product"
      ],
      "extensions": {
        "code": "ENTITY_NOT_FOUND"
      }
    }
  ],
  "data": {
    "activeCustomer": null
  }
}
