Initialize swiper

Question

我已经进行了一些api调用后试图初始化我的swiper容器。但是，当我这样做时，我得到错误类型'元素'上不存在'刷卡器'。这是Swiper API的链接：Swiperjs

  ngOnInit() {
    this.spinner.show().then( async () => {
      this.data.currentProgress.subscribe(progress => this.progress = progress);
      await this.eventService.fetchEvents();
      }).then(async () => {
        const mySwiper = document.querySelector('.swiper-container').swiper;
        mySwiper.init();
      }).then(() => {
        this.spinner.hide();
      });
  }
