我最近升级到了Rails 5。在升级和修复了一些常见的东西之后，我的应用程序似乎运行正常，并提供了响应

即使我的测试套件以94%的覆盖率通过，但在执行实际请求时，控制器在声称请求是

200 OK

后崩溃

看起来堆栈跟踪并没有指向我的应用程序中的任何代码，而是指向Actionpack中的某些代码

这是我的一个错误配置，还是Rails 5中的一个合法错误

在141ms内完成200 OK（视图：2.2ms |活动记录：124.9ms）

我发现了问题。在应用程序的Rails 4天中，我。在Rails 5中，它似乎不再是散列。我现在使用

reset\u session

代替

request.session\u options={}

这是在测试浏览器中的页面还是在为其提供服务？您是否有可以尝试删除的活动会话？（可能有一些旧数据？）提供实际的JSON文档。我在Rails 4（升级前）中禁用了Cookie和会话，因为它是一个API。是否有可能您的中间件堆栈的一部分正在尝试对会话执行某些操作，但它失败了，因为它被禁用了？我对此表示怀疑，但我在堆栈跟踪中没有看到任何自定义中间件。只是一堆Rails的东西。酷，你应该添加它作为答案。
