laravel-admin报错Disk [admin] not configured

报错（Disk [admin] not configured, please add a disk config in config/filesystems.php.）

新部署的laravel-admin出现过这个错误，我在config/filesystems.php的disks数组里面添加上

'disks' => [    
        'local' => [
            'driver' => 'local',
            'root'   => storage_path( 'app' ),
        ],
        'public' => [
            'driver'     => 'local',
            'root'       => storage_path( 'app/public' ),
            'url'        => env( 'APP_URL' ) . '/storage',
            'visibility' => 'public',
        ],
        's3'    => [
            'driver' => 's3',
            'key'    => env( 'AWS_ACCESS_KEY_ID' ),
            'secret' => env( 'AWS_SECRET_ACCESS_KEY' ),
            'region' => env( 'AWS_DEFAULT_REGION' ),
            'bucket' => env( 'AWS_BUCKET' ),
            'url'    => env( 'AWS_URL' ),
        ],
        //新增的数组
        'admin' => [
            'driver' => 'local',
            'root' => public_path('upload'),
            'visibility' => 'public',
            'url' => env('APP_URL') . '/upload/',
        ],
    ],

添加上这数组后问题依然没有解决，有其他小伙伴遇到过这种情况么？
