HarmonyOS 旧版API提示错误

项目中的Tabs用到了如下方法：

.onAnimationStart((index: number, targetIndex: number, event: TabsAnimationEvent) => {
  // 切换动画开始时触发该回调。下划线跟着页面一起滑动
  this.focusIndex = targetIndex
  Logger.info('Safe', ' 切换动画开始时触发该回调，下标' +this.focusIndex);
  let targetIndexInfo = this.getTextInfo(targetIndex)
  this.startAnimateTo(this.animationDuration, targetIndexInfo.left, targetIndexInfo.width)
})

private getTextInfo(index: number): Record<string, number> {
    let strJson = getInspectorByKey(index.toString())
    try {
    let obj: Record<string, string> = JSON.parse(strJson)
    let rectInfo: number[][] = JSON.parse('[' + obj.$rect + ']')
    return { 'left': px2vp(rectInfo[0][0]), 'width': px2vp(rectInfo[1][0] - rectInfo[0][0]) }
  } catch (error) {
    return { 'left': 0, 'width': 0 }
  }
}

其中getInspectorByKey()这个方法报错，显示是过时了，新版API是什么？
