请求提供移除JSON根元素的JOLT转换规则

以下是满足需求的JOLT Specification：

[
  {
    "operation": "shift",
    "spec": {
      "RootElement": ""
    }
  }
]

说明： #

• 使用shift操作类型，将输入中RootElement对应的数组直接映射到输出的根节点（空字符串""代表根层级），从而移除原有的根元素包装。

输入示例： #

{
  "RootElement": [
    {
      "External_Contact_ID": "6504668",
      "Email_Address": "test@gmail.com",
      "First_Name": "Test_Name",
      "Last_Name": "TestLastName",
      "Member_STATUS": "ACTIVE"
    },
    {
      "External_Contact_ID": "6506709",
      "Email_Address": "test1@gmail.com",
      "First_Name": "Test_Name1",
      "Last_Name": "TestLastName1",
      "Member_STATUS": "ACTIVE"
    }
  ]
}

输出结果： #

[
  {
    "External_Contact_ID": "6504668",
    "Email_Address": "test@gmail.com",
    "First_Name": "Test_Name",
    "Last_Name": "TestLastName",
    "Member_STATUS": "ACTIVE"
  },
  {
    "External_Contact_ID": "6506709",
    "Email_Address": "test1@gmail.com",
    "First_Name": "Test_Name1",
    "Last_Name": "TestLastName1",
    "Member_STATUS": "ACTIVE"
  }
]
