OPPO Reno、OPPO R11t手机 报 getMenuButtonBoundingClientRect:fail;

运维中心报错信息：

getMenuButtonBoundingClientRect:fail; at wx.getMenuButtonBoundingClientRect Error: getMenuButtonBoundingClientRect:fail at Object.getMenuButtonBoundingClientRect (WASubContext.js:1:978159) at Object.

(WASubContext.js:1:379691) at Object.(WASubContext.js:1:997145) at Function.(WASubContext.js:1:997275) at Object.(WASubContext.js:1:365715) at ye.attached (https://component/navigation-bar/index.js:44:32)

这个方法到底是异步还是同步？ 如果是异步，也没个回调，即使用了try catch也没用 ，catch不住异步函数的异常。
