问题描述：
之前给公司做了个小程序，上线之后没有问题，审核也通过了，近期有需求做了一些更改（改动不大），这是背景。
然后这次提交审核之后，被驳回了，原因是小程序无法正常使用，看了下审核反馈的截图，登录未成功，报错了。
我立马用体验版测试，因为体验版就是审核的代码，后台连接的服务器程序也是完全一致的，结果亮点来了，我体验版**完美运行**
后来又测试了本地版本，又用了各种方式测试了体验版本，都没有问题，再次提交审核，不出意外，又毙了。。
拉出审核人员登录时的后台日志：

可以看到数据库报了个错，但是这个错什么原因目前查不出来，而且我们无法复现，我们测试一切正常，只要审核人员登录就会报这个错误。
有没有大神指导一下，现在头都大了。。。
