Rxjs订阅在Angular 10.1.1和rxjs 6.6.3的IE 11中不起作用

问题描述

从Angular 10.0.1升级到10.1.1后，IE 11停止工作。尝试订阅（rxjs ^ 6.6.3）甚至最简单的http请求都将引发错误：“ TypeError：Invalid calling object”。 Chrome可以正常运行。请帮忙！

service.ts

test() {
    const apiHeader = new HttpHeaders()
        .set('Content-Type','application/json')
        .set('cache-control','no-cache');

    const url = decodeURIComponent(`https://.../api/test/test`);
    return this.http.get<any>(url);
}

app.component.ts

  ngOnInit() {
    this.myService.test()
      .pipe(take(1))
      .subscribe(data => {
        console.log('ngOnInit',data)

      },err => {
          console.log('err',err)
        });
  }
