升级至最新版1.02.1905081编译预览经常不过，是bug吗？ - WXOPEN Club

当前 Bug 的表现（可附上截图）

自动预览

多次错误编译后，居然通过了。

自动上传也是如此，自动上传需要clear所有文件后，重新生成，所以一直没过，是否编译时有缓存，并发之类的，导制通过不了？

预期表现

一次性编译预览通过，但总是不通过，然后多进行几次又莫名通过，在IDE中直接点击预览、上传均出现同样问题。

复现路径

提供一个最简复现 Demo

fengna 1楼•3 年前

对了，经常出现的 Cannot read property ‘contexts’ of null ，在源代码的文件里并没有 contexts，这个contexts是否是编码过程产生的？
