I am facing issue while upgrading Laravel 5.3 from 5.2.

Following Error occurs

 ReflectionException: Class does not exist in /MYPROJECT/vendor/laravel/framework/src/Illuminate/Container/Container.php:749

    Have you read the upgrade instructions? – Andy Holmes May 08 '18 at 08:26
  • Yes i gone through the upgrade guide... – Peter Neil May 08 '18 at 08:29
  • Andy, Can you help me out for this issue? I don't know what I have made wrong with this upgrade process. – Peter Neil May 08 '18 at 08:53
  • Try deleting ./vendor folder and doing `composer update` (if you changed composer.json already reflecting upgrade instructions!) Also try doing `composer dump-autoload -o` -- if that solves your problem you have namespace / autoloading problem. – Kyslik May 08 '18 at 09:24
  • Actually my project was in 5.0 version, so i just go through the upgrade process like 5.1, 5.2 and reach to upgrade 5.3. But in 5.3 upgrade process produces above error. Also I am using custom auth controller and composer dump-autoload also not working. – Peter Neil May 08 '18 at 09:29

Thanks for your effort but i have found the issue regarding the given error. It was due to middleware value in RouteSeriveProvider.php file. By mistake I have set its value as blank and it could not find any middleware, so it produces above error.

app/Providers/RouteServiceProvider.php file in mapWebRoutes I did set middleware value as blank. If you do not want to provide any middleware then remove the whole middleware line.
