Visual Studio 的 Azure 流分析工具：执行聚合查询时出错 - "Object reference not set to an instance of an object"

Question

我们已遵循文档 Use Azure Stream Analytics tools for Visual Studio 并使 Visual Studio 能够创建 Azure 流分析项目。

我们已经使用以下 JSON 格式的本地输入数据创建了 Azure 流分析 (ASA) 作业：

[
    {
        "Driver": "Lewis",
        "Speed": 0.8275496959686279,
        "Accelerator": 1,
        "Brakes": 0,
        "Steering": 0,
        "ErsBattery": 0.9398990273475647,
        "Gear": 0,
        "LapTimeMs": 107,
        "EventTime": "2016-04-01T00:00:00.107",
        "PosX": 1593.4061279296875,
        "PosY": 934.5406494140625,
        "PosZ": 101.44535064697266
    },
    {
        "Driver": "James",
        "Speed": 1.8795902729034424,
        "Accelerator": 1,
        "Brakes": 0,
        "Steering": 0,
        "ErsBattery": 0.9865896105766296,
        "Gear": 0,
        "LapTimeMs": 107,
        "EventTime": "2016-04-01T00:00:00.107",
        "PosX": 1593.3990478515625,
        "PosY": 934.5374145507812,
        "PosZ": 101.44610595703125
    },
    {
        "Driver": "Damon",
        "Speed": 0.4023849666118622,
        "Accelerator": 1,
        "Brakes": 0,
        "Steering": 0,
        "ErsBattery": 1,
        "Gear": 0,
        "LapTimeMs": 108,
        "EventTime": "2016-04-01T00:00:00.108",
        "PosX": 1593.411865234375,
        "PosY": 934.5435180664062,
        "PosZ": 101.44485473632812
    }
]

然后我们运行查询本地如下：

SELECT Driver, AVG(Speed) AS AvgSpeed
FROM Input 
GROUP BY Driver, TumblingWindow(second, 10)

执行查询后，我们收到错误消息“错误：对象引用未设置为对象的实例。”

在管理员模式下打开 Visual Studio IDE，运行使用 本地输入 的 ASA 查询，您将获得预期的查询结果.
