这是哪里报错？无从排查 - WXOPEN Club

小程序在开发工具里运行没有报错，一切正常。在手机上预览时，在小程序控制台看到了报错，小程序的后台也记录了：

Cannot read property 'forEach' of undefined;at api request complete callback function

TypeError: Cannot read property 'forEach' of undefined

at complete (app-service.js:1634:748)

at Object.o.complete (WASubContext.js:1:1086631)

报错信息里不是写了吗

你在某一个complete函数里对一个值为undefined的变量forEach了

全局搜索一下咯
