问是否有方法将复杂的条件定义为变量？

EN

query ($first:Int, $page:Int) {
    my_listings(
        where: {
            AND: [
                { column: NET_AREA, operator: GTE, value: 200 }
            ]
        }
        orderBy: [
            { column: ID, order: ASC }
            ]
        first: $first
        page: $page
    ) {
        data {
            ...listingFields
        }
        paginatorInfo {
            currentPage
            lastPage
        }
    }
}

query($first: Int, $page: Int, $conditions:MyListingsWhereWhereConditions) {
  my_listings(
    where: $conditions
    orderBy: [{ column: ID, order: ASC }]
    first: $first
    page: $page
  ) {
    data {
      ...listingFields
    }
    paginatorInfo {
      currentPage
      lastPage
    }
  }
}

{
  "first": 1,
  "page": 1,
  "conditions": {"AND": {"column": "PRICE", "operator": "LTE","value": "190"}}
}

Variable \"$conditions\" got invalid value {\"AND\":{\"column\":\"PRICE\",\"operator\":\"LTE\",\"value\":\"190\"}}; Expected type MyListingsWhereWhereConditions to be an object at value.AND.column.
