Bot Framework提供遥测ArgumentNullException telemetryClient错误

问题描述 投票:0回答:1

在稳定了具有多个对话框的4.5.3机器人之后,现在我决定实现遥测。我相信我会在文档和示例核心bot之后找到所有内容,但通常在替换或重新启动对话框时,经常会出现此错误。

ArgumentNullException:值不能为null。参数名称:telemetryClient

编辑:我尝试将所有相关的依赖项升级到4.6.3,但问题仍然存在。

它发生在OnTurnAsync内部MYBOT.cs的第94行:

var conversationData = await _conversationDataAccessor.GetAsync(turnContext, () => new ConversationData());

用户状态/用户配置文件没有问题。

ConversationData只是示例中包含Timestamp的简单类(我删除了ChannelId)。

完整堆栈跟踪:

因此,我通过抓取整个Bot Framework SDK的源代码并对其进行调试来自己解决了问题。

我正在使用瀑布对话框,并且它们的状态通过ConversationState持久保存在JSON的存储中,如下所示:

{
    "$type": "Microsoft.Bot.Builder.Dialogs.DialogInstance, Microsoft.Bot.Builder.Dialogs",
    "id": "WaterfallDialog",
    "state": {
        "$type": "System.Collections.Generic.Dictionary`2[[System.String, System.Private.CoreLib],[System.Object, System.Private.CoreLib]], System.Private.CoreLib",
        "options": {
            "$type": "VFatumbot.MainDialog, VFatumbot",
            "id": "MainDialog",
            "InitialDialogId": "WaterfallDialog",
            "TelemetryClient": {
                "$type": "Microsoft.Bot.Builder.ApplicationInsights.BotTelemetryClient, Microsoft.Bot.Builder.ApplicationInsights"
            }
        },
        "values": {
            "$type": "System.Collections.Generic.Dictionary`2[[System.String, System.Private.CoreLib],[System.Object, System.Private.CoreLib]], System.Private.CoreLib"
        },
        "instanceId": "6a5f8aba-61de-4d3b-a13c-eed970fce895",
        "stepIndex": 0
    },
    "StackIndex": null
}

并且尝试读回JSON时,它试图使用构造函数的空参数实例化BotTelemetryClient:

public BotTelemetryClient(TelemetryClient telemetryClient)
        {
            _telemetryClient = telemetryClient ?? throw new ArgumentNullException(nameof(telemetryClient));
        }

源代码:https://github.com/microsoft/botbuilder-dotnet/blob/master/libraries/Microsoft.Bot.Builder.ApplicationInsights/BotTelemetryClient.cs

尽管很可能不是通过使用telemetryClient = telemetryClient来解决此问题的正确解决方案;代替。
