laravel 5 development.ERROR

我随机得到这个错误，我搜索它，似乎如果你没有设置一个应用程序密钥，这种情况会发生，问题是我从一开始就设置了它。这个问题通常发生在我从我的应用程序中进行多个$http调用时，它从不发生在postman中。

更新:我再检查一下然后修改app。php

'key' => env('APP_KEY', 'someRandomString')

with my key

'key' => env('APP_KEY', 'My key')

在路由上找不到404错误。我认为在某些时候随机无法读取嫉妒键。这可能是我在电脑上开发的资源有问题，我将把它上传到服务器并再次检查。
