lottile动画加载完成回调不调用

Canvas(this.canvasRenderingContext) 
  .width(360 + ‘px’) 
.height(360 + ‘px’) 
.backgroundColor(Color.Gray) 
  .onReady(() => { 
    // 可在此生命回调周期中加载动画，可以保证动画尺寸正确 
    this.animateItem = lottie.loadAnimation({ 
      container: this.mainCanvasRenderingContext, 
      renderer: ‘canvas’, 
      loop: true, 
      autoplay: true, 
      //name: this.animImageParams?.animateName, 
      //path: this.animImageParams?.animatePath, 
    }) 
    console.info(this.TAG, "animateItem " + this.animateItem); 
    // Console.info(this.TAG, “lottie DOMLoaded 2”); 
    this.animateItem.addEventListener(‘DOMLoaded’, (args: Object): void => { 
      console.info(this.TAG, “lottie DOMLoaded=========”); 
      this.isCanvasVisible = Visibility.Visible 
    }); 
    // Console.info(this.TAG, “lottie DOMLoaded 3”); 
    this.animateItem.addEventListener(‘segmentStart’, (args: Object): void => { 
      console.info(this.TAG, “lottie segmentStart=========111”); 
    }); 
  })
