Adal Angular5 Adal5Service.acquireToken因“由于超时而导致令牌更新操作失败”而失败，但是网络中存在成功的请求

尝试使用adal-angular5并遇到Adal5Service.acquireToken方法问题：它总是与以下内容有关：

令牌更新操作由于超时而失败

StackBlitz上的在线完整示例。去测试：

• 贴上你的房客
• 粘贴您的clientId
• https://angular-96tws9.stackblitz.io在Azure Portal中为您的应用注册URL
• 在新窗口中打开

这里是app.component.ts：

import { Component, OnInit } from '@angular/core';
import { Adal5Service } from 'adal-angular5';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  constructor(private adalSvc: Adal5Service) {
    let config: adal.Config = {
      tenant: 'XXX.onmicrosoft.com',
      clientId: '21efffd5-29fc-XXX',
      postLogoutRedirectUri: window.location.origin,
      endpoints: {
        graphApiUri: "https://graph.microsoft.com",
      },
      cacheLocation: "localStorage",
      redirectUri: ''
    };

    this.adalSvc.init(config);
  }

  ngOnInit(): void {
    this.adalSvc.handleWindowCallback();

    if (!this.adalSvc.userInfo.authenticated) {
      this.adalSvc.login();
      return;
    }

    // work correct
    console.log(this.adalSvc.userInfo.username);

    this.adalSvc.acquireToken("https://graph.microsoft.com")
      .subscribe(
        token => console.log(token), // never comes
        error => console.log(error)); // error: Token renewal operation failed due to timeout
  }
}

网络中有正确的获取令牌：
