Why in place 404 error 500?

Question

Laravel

Before that, I gave 404 to a non-existent page. I rolled up the new laravel installed the old APP and views.
But I noticed that it gives 500 instead of 404 to the existing page. The 404 page exists.
Chrome debug says Status Code: 500 Internal Server Error

Answer 1

The problem was solved by updating the project
php artisan view:clear
php artisan cache:clear
composer update --no-dev --optimize-autoloader
After that, a variable missing error was written to the log.

Answer 2

And look at the logs (storage/logs/), don't you? =)
