Javascript 量角器-元素未附加到页面文档

所以伙计们，和很多人一样的问题！当我尝试在页面中交互（单击）某个元素时，出现以下错误：

错误消息

失败：过时元素引用：元素未附加到页面 “文件”

我理解了页面改变DOM的概念，但我真的无法解决这个问题。有什么建议吗？ （元素出错：等待processoLista.click（）；）

哪一行导致了问题？您能发布完整的堆栈跟踪吗？@Sureshmani出错的元素是wait processoLista.click（）；我相信在aplicar.click（）之后还会发生其他一些进程/事件，这会影响下一个元素processoLista。您是否尝试添加静态等待？虽然不建议这样做，但通过这种等待更容易隔离问题。
