Class "Redis" Not Found laravel 8, using phpredis

Question

I am using laravel 8, and it is throwing error, when ever I tried to run:

php artsian config:clear

On laravel, this is my config value (because I am trying to use phpredis):

'client' => env('REDIS_CLIENT', 'phpredis'),

I could use redis-cli and ping at the moment. Not, just that I could hit the following endpoint successfully.

    public function testRedis()
    {
        Redis::set('ping','pong');
        $ping = Redis::get('ping');
        dd($ping);
    }

It prints out pong successfully.

but I am receiving class Redis not found. Whenever I tried to run, php artisan config:clear

Full error looks like this:

  Class "Redis" not found

and my App\Models\Setting looks like:

use Illuminate\Support\Facades\Cache;

class Setting extends Model
{

    protected $table = 'settings';
    protected $guarded = ['id'];
    protected $dates = ['created_at','updated_at'];

    /**

     */
    protected $casts = [
        'created_at' => 'datetime:Y-m-d', // Change your format
        'updated_at' => 'datetime:Y-m-d',
    ];

    const STRIPE_ENVIRONMENT = ['test', 'live'];

    public static function getCachedValue(){
        return Cache::rememberForever('settings', function () {
            return Setting::pluck('key_value', 'key_name');
        });
    }

    public static function updateCachedSettingsData(){
        Cache::forget('settings');
        self::getCachedValue();
    }
}

What, I might be doing wrong here. #PS: This line on my config/app is commented.

// 'Redis' => Illuminate\Support\Facades\Redis::class,

you must specify "REDIS CLIENT" in your .env file after installation

composer require predis/predis

in the .env file add these lines

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379
REDIS_CLIENT=predis
