'Error when setting up the application in laravel 5

I am trying to composer update the command on my existing laravel5.8 project. For that I run the below command : "composer update".

Laravel get updated without any fail and after that I tried to clear the config and cache..but when I tried to do so I am getting the below error for every action

In Container.php line 788:

Class seed.handler does not exist

When I run the website locally , I get 500 error and apache logs say : PHP Fatal error: Uncaught ReflectionException: Class view does not exist in /var/www/html/pombackend/vendor/laravel/framework/src/Illuminate/Container/Container.php:788

I searched everywhere but did not get the fix for this. Can anybody help me with this ?

Put this in your composer.json file:

 "config": {

    "preferred-install": "dist",
    "sort-packages": true,
    "optimize-autoloader": true,
    "allow-plugins": {
        "composer/installers": true,
        "dealerdirect/phpcodesniffer-composer-installer": true,
        "roots/wordpress-core-installer": true
    }
},

 

Hope so it will work.
