HarmonyOS Lottie文件能显示，但不会做动画

build() {
  Column() {
    /// GuaguaLoading
    Canvas(this.renderingContext)
      .width(Zoom(144))
      .height(Zoom(144))
      .onReady(() => {
        console.log("GuaLessonLoadingProgress lottie loadAnimation");
        lottie.loadAnimation({
          container: this.renderingContext,
          renderer: 'canvas',
          loop: true,
          autoplay: true,
          name: this.animateName,
          path: this.animatePath,
        });
      })
      .onDisAppear(() => {
        console.log("GuaLessonLoadingProgress lottie destroy");
        lottie.destroy(this.animateName);
      })
  }
  .width('100%')
  .height('100%')
  .backgroundColor(Color.White)
