使用Application Insights跟踪自定义错误的问题：TypeError：无法读取未定义的属性“ stack”

问题描述

我已经编写了一个自定义错误类，并希望使用Azure Application Insights跟踪错误。我正在使用Node.js。当我尝试跟踪自定义错误时，出现以下错误：

TypeError: Cannot read property 'stack' of undefined
    at Function.EnvelopeFactory.createExceptionData (/Users/liam/Desktop/CustomError/node_modules/applicationinsights/out/Library/EnvelopeFactory.js:145:40)
    at Function.EnvelopeFactory.createEnvelope (/Users/liam/Desktop/CustomError/node_modules/applicationinsights/out/Library/EnvelopeFactory.js:32:40)
    at NodeClient.TelemetryClient.track (/Users/liam/Desktop/CustomError/node_modules/applicationinsights/out/Library/TelemetryClient.js:116:44)
    at NodeClient.TelemetryClient.trackException (/Users/liam/Desktop/CustomError/node_modules/applicationinsights/out/Library/TelemetryClient.js:69:14)
    at Object.<anonymous> (/Users/liam/Desktop/CustomError/app.js:10:8)
    at Module._compile (internal/modules/cjs/loader.js:1138:30)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1158:10)
    at Module.load (internal/modules/cjs/loader.js:986:32)
    at Function.Module._load (internal/modules/cjs/loader.js:879:14)
    at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:71:12)

代码如下：

class CustomError extends Error {  
    constructor (message) {
      super(message)
      
      Error.captureStackTrace(this,this.constructor);
      this.name = this.constructor.name;
      this.status = 404;
    }
  
    statusCode() {
      return this.status
    }
}

const appInsights = require('applicationinsights');
appInsights.setup('MY_KEY').start();
let client = appInsights.defaultClient;

const customError = require('./exceptions');
let newError = new customError('The custom error was thrown')

client.trackException(newError);

我已经基于其他在线资源对TelemetryClient对象进行了一些研究，但我认为这不是正确的方向。

我正在使用此资源作为指南：https://docs.microsoft.com/en-us/azure/azure-monitor/app/api-custom-events-metrics#trackexception

解决方法

我能够通过将一个键值对传递给trackException来解决此问题，其中键是异常，值是错误：

client.trackException({exception: new customError('This is a custom error')});

完整代码：

class CustomError extends Error {  
    constructor (message) {
      super(message)
      
      Error.captureStackTrace(this,this.constructor);
      this.name = this.constructor.name;
      this.status = 404;
    }
  
    statusCode() {
      return this.status
    }
}

const appInsights = require('applicationinsights');
appInsights.setup('MY_KEY').start();
let client = appInsights.defaultClient;

client.trackException({exception: new CustomError('This is a custom error')});
