AddPlayerPacket and UUID

I'm trying to add a player packet to a client when they join but in order to do so you need to add a UUID instance to the Packet. I've tried a ton of different things and I can't get them to work.

If somebody can tell me how to get the UUID class to generate a UUID or some alternative way that still uses packets that'd be great.

Code:

PHP:

//The required Classes
use pocketmine\network\protocol\AddPlayerPacket;
use pocketmine\utils\UUID;
//Skip to the functions
public function __construct(Player $player, $kitId, $eid, $name, $description, Vector3 $pos, $skin, $slim = false) {
        $this->player = $player;
        $this->kitId = $kitId;
        $this->eid = $eid;
        $this->uuid = UUID::fromData($eid, $skin, $name);
        $this->username = $name;
        $this->description = $description;
        $this->pos = $pos;
        $this->skin = $skin;
        $this->slim = $slim;
      
        $this->sendPacket();
    }
  
    public function sendPacket() {
        $pk = new AddPlayerPacket();
        $pk->eid = $this->eid;
        $pk->clientID = $this->uuid;
        $pk->username = $this->createUsername();
        $pk->x = $this->pos->x;
        $pk->y = $this->pos->y;
        $pk->z = $this->pos->z;
        $pk->pitch = 0;
        $pk->yaw = 270;
        $pk->skin = $this->skin;
        $pk->isSlim = $this->slim;
        $this->player->dataPacket($pk);
    }


Error:

I've already extensively looked at UUID.php, all the __construct function has defaults for all the variables.
I've also looked at the Human.php class and this is how it creates a UUID instance.

You have to set the UUID field for the packet with an instance of UUID.

So

PHP:

$pk->uuid = $this->uuid;


?

Have you looked at Specter by @Falk?

Specter spawns a player like he connected from a real client. Specter does not handle anything about spawning players, etc. Specter is basically a plugin that creates a new connection to the server without MCPE.
