接入小程序开屏广告后，小程序后台we分析-js分析里有很多报错如下，具体报错的原因是什么？
undefined is not an object (evaluating \'a.adMaterial.style\')
undefined is not an object (evaluating \'a.adMaterial.src=pm\')
undefined is not an object (evaluating \'a.adMaterialBg.src=hm\')
undefined is not an object (evaluating \'a.adMaterialBg.src=ym\')
undefined is not an object (evaluating \'a.adMaterial.src=ep\')
已知问题，修复中，不影响C端体验，仅会产生报错
端午节后，报错的问题，应该也会Fix
