Uncaught ReflectionException: Class env does not exist after upgrade to Laravel 5.6

Question

After upgrading to Laravel from 5.5 to 5.6.12 I get following exception:

PHP Fatal error: Uncaught ReflectionException: Class env does not exist in /var/www/showroom-ng/vendor/laravel/framework/src/Illuminate/Container/Container.php:767 Stack trace: 0 /var/www/showroom-ng/vendor/laravel/framework/src/Illuminate/Container/Container.php(767): ReflectionClass->__construct('env') 1 /var/www/showroom-ng/vendor/laravel/framework/src/Illuminate/Container/Container.php(646): Illuminate\Container\Container->build('env') 2 /var/www/showroom-ng/vendor/laravel/framework/src/Illuminate/Container/Container.php(601): Illuminate\Container\Container->resolve('env', Array) 3 /var/www/showroom-ng/vendor/laravel/framework/src/Illuminate/Foundation/Application.php(747): Illuminate\Container\Container->make('env', Array) 4 /var/www/showroom-ng/vendor/laravel/framework/src/Illuminate/Container/Container.php(1210): Illuminate\Foundation\Application->make('env') 5 /var/www/showroom-ng/vendor/laravel/framework/src/Illuminate/Foundation/Application.php(492): Illuminate\Container\Container->offsetGet('env') 6 /var/www in /var/www/showroom-ng/vendor/laravel/framework/src/Illuminate/Container/Container.php on line 767

I don't see anything related in the upgrade guide.

I tried to dig into Laravel internals, and for example removing code:

    if (! $app->environment('testing')) {
        ini_set('display_errors', 'Off');
    }

from vendor/laravel/framework/src/Illuminate/Foundation/Bootstrap/HandleExceptions.php removes one occurrence of mentioned exception, but there is some other place which is causing the same one. I tried to use lower 5.6 versions of Laravel, but it doesn't change anything.

It would probably be relevant to tell us what you upgraded from, and the full stack trace of the problem. The most common problem is a bad config file. Other causes could be that you have overridden the $bootstrappers array in any of your kernels and forgot the LoadConfiguration bootstrapper. — sisve
@sisve I updated from 5.5. I don't override any $bootstrappers, And I pasted the whole message which I get in the browser or in the — Pawel Ryznar

So problem was with other exception which was occurring in Exception handler! when calling app()->environment() , which was hiding the real exception, which was related to trusted proxies https://stackoverflow.com/a/48595052/6852455
