微信后台错误日志：

Cannot read property 'getAbsolutePosition' of undefined;at setTimeout callback function TypeError: Cannot read property 'getAbsolutePosition' of undefined at o.rh (https://lib/WAGame.js:1:624386)at Function.(https://lib/WAGame.js:1:624631)at https://lib/WAGame.js:1:220552at https://lib/WAGame.js:1:87613

游戏内并没有getAbsolutePosition的接口和调用。

请问这是什么错误？
