这个错误对 nodejs 配置中的 MSAL 意味着什么？

Question

I want to configure MSAL with Nodejs. But I am getting error from terminal that when I execute this line.

The error I am getting is :

(node:25500) UnhandledPromiseRejectionWarning: TypeError: this.getTelemetryManagerFromConfig is not a function

This is the Code:

var msal = require('msal');
    // var adal = require('adal-node');
    var fs = require('fs');
    var https = require('https');

    var config = require(__dirname + '/config.json');
    console.log(config);
    console.log(msal);
    **const msalInstance = msal.UserAgentApplication(config);
    console.log(msalInstance);**

Here is my config file.

{
    "authorityUrl" : "https://login.microsoftonline.com/common/",
    "resourceUrl" : "https://analysis.windows.net/powerbi/api",
    "apiUrl" : "https://api.powerbi.com/",
    "appId" : "**********************************",
    "clientId" : "**********************************",
    "workspaceId" : "**********************************",
    "reportId" : "**********************************",
    "username" : "**********************************",
    "password" : "********************"
}

Here is the function where this shows the error at msal/lib-commonjs/UserAgentApplication.js File:

 function UserAgentApplication(configuration) {
        // callbacks for token/error
        this.authResponseCallback = null;
        this.tokenReceivedCallback = null;
        this.errorReceivedCallback = null;
        // Set the Configuration
        this.config = Configuration_1.buildConfiguration(configuration);
        // Set the callback boolean
        this.redirectCallbacksSet = false;
        this.logger = this.config.system.logger;
        this.clientId = this.config.auth.clientId;
        this.inCookie = this.config.cache.storeAuthStateInCookie;

        **this.telemetryManager = this.getTelemetryManagerFromConfig(this.config.system.telemetry, this.clientId);** //error is referring to this line.
}

Please help. Thanks in Advance.

When you create your instance of UserAgentApplication, use

const msalInstance = new msal.UserAgentApplication(config);

Emphasis on the keyword new :)
