Lumen after upgradation from 5.7 to 6.0 db:seed command not working - composer-php

Question

I have upgraded from Lumen 5.7 to 6.0. After the upgradation, the artisan db:seeder command is not working. It shows Target class [DatabaseSeeder] does not exist. I have tried running composer dump-autoload but it didn't solve the problem. Below is the composer.json file
{
"name": "laravel/lumen",
"description": "The Laravel Lumen Framework.",
"keywords": [

},

},
"scripts": {

Please help

Laravel changed directory of seeders class, (from database/seeds to database/seeders) so you probably need to update your composer.json this way (move seeders in autoload /psr-4):
"autoload": {
"psr-4": {
"App\\": "app/",
"Database\\Factories\\": "database/factories/",
"Database\\Seeders\\": "database/seeders/"
},
"files": [
"app/helpers/helpers.php"
]
},
And add namespace to your seeders files :
<?php
namespace Database\Seeders;
use Illuminate\Database\Seeder;
class DatabaseSeeder extends Seeder
{
....
Don't forget to run composter dump-autoload after updating your files.
