Date 错误未知类型“；日期时间“；关于gql的阿波罗有效载荷

我有很多问题，但这次我的问题是GraphQL及其负载，我的

schema.gql

和

resolvers.js

文件如下所示：

    # schema.gql
    scalar GraphQLDateTime
    scalar GraphQLDate
    scalar GraphQLTime
    
    type Query {
      magicQuery(
        idMagic: Int
        magicDate: GraphQLDateTime
      ): DamnWow
    }
    
    type DamnWow {
      _id: String
      magicDateResult: GraphQLDateTime
    }

当我尝试将有效负载用于这样的查询时：

    # query
    query magicQuery($idMagic: Int, $magicDate: DateTime) {
      magicQuery(idMagic: $idMagic, magicDate: $magicDate) {
        _id
        magicDateResult
      }
    }
    
    # variables
    # {
    #   "idMagic": 1,
    #   "magicDate": "2007-12-03T10:15:30Z"
    # }

它将返回一个错误：

      "error": {
        "errors": [

          }

      }
    }

如果我在代码中使用相同的参数directy，它就可以正常工作

有人知道此错误的原因吗？

架构中的标量类型名称是

GraphQLDateTime

，但在请求中使用的是

DateTime

尝试将请求更改为：

query magicQuery($idMagic: Int, $magicDate: GraphQLDateTime) {
  magicQuery(idMagic: $idMagic, magicDate: $magicDate) {
    _id
    magicDateResult
  }
}

---

只是模式中没有

DateTime

type/scalar。。。在查询（arg类型）中尝试

GraphQLDateTime

？这很有效。非常感谢。

query magicQuery($idMagic: Int, $magicDate: GraphQLDateTime) {
  magicQuery(idMagic: $idMagic, magicDate: $magicDate) {
    _id
    magicDateResult
  }
}
