未捕获(承诺中):[对象未定义]

我在Internet Explorer中遇到了这个具体错误(“未捕获(承诺):[对象未定义]”),该错误似乎与polyfill有关。当在加载少量JavaScript文件的同时创建新的Promise时,似乎正在发生这种情况。我没有在其他浏览器中看到此问题,这使我认为这可能是一个polyfills问题。

以下是我的polyfills.js文件中的内容:

import 'zone.js/dist/zone';  
import 'core-js/es7/object';
import 'core-js/es7/array';

以下是创建Promise的代码:

export const loadFile = () => {
  return new Promise((resolve, reject) => {
    loadScript('scripts/jquery-1.11.1.min.js').then(
      () => {
        loadScript((window as any).someUrl).then(
          () => { resolve(); },
          () => { reject(); },
        );
      },
      () => {
        reject();
      }
    );
  });
};

不确定我缺少什么。这是我在开发人员工具中看到的错误
