phpredis scan method laravel

Question

Running my application inside a redis cluster and I stumbled about a strange issue:

dd(Redis::connection('default')->scan('0', [
    'match' => 'my_application_cache_*',
    'count' => 999,
]));

returns:

array:2 [▼ // app/Http/Controllers/User/ProfileController.php:30
  0 => 1
  1 => []
]

Running the same command with redis-cli like:

127.0.0.1:6379> scan 0 MATCH my_application_cache_* COUNT 9999

returns:

1) "0"
2)  1) "my_application_cache_:SLY6WWj9cymyZzJk0BihOYAm7uNQT9T55bYrvGMB"
    2) "my_application_cache_:IDF8Qe713Y06XOEmaQC7mzyupKgURusIaTxLt1Nx"
    3) "my_application_cache_:4JRZ1Zd8hg2FwQzO5JTRlWuyxIi07V0ERqXtAVer"
    4) "my_application_cache_:GWv8tisv4xQAgBaXdJap62aJh95V5mWvTiw9CQ0X"
    5) "my_application_cache_:hTKTDsUN9YsuuHlxJdFSflL737MvvPZPX0O9uNLQ"

Any idea why laravel isn't returning any values inside the 1 element of the array?
