3.8.10饼图交互事件的例子打开报错

报错提示Ctor is not a constructor，我在钉钉小程序使用也遇到这个问题

Start by reproducing the 3.8.10 pie-chart interaction example and the reported DingTalk mini-program scenario. Trace where the “Ctor is not a constructor” error originates and compare the example’s interaction setup across those environments. Done means the example opens without the error and the affected interaction path is covered by a regression check.
