Solved Armorstands HELP! :(

UPDATE: I found my own problem. I was passing a Player instead of a String to the armorStands map. I'll leave me code here though for anyone that might be looking for some help with Armor Stands!

---------------------------------------------------------------------------------------------------------------------------------------

Hey there. So I'm making a 1:1 League of Legends plugin. When players select a "champ", an armor stand appears with their head, a few items from that champ, and the champ's name above the armorstand.

Now, the code below was working perfectly earlier. Now, it's throwing a NullPointerException at "armorStands.get(player).setCustomName(PlayerInfo.getPI(player.getName()).getChamp());" I've checked to make sure that armorStands.get(player) isn't returning null and that PlayerInfo.getPI(player.getName()).getChamp() isn't returning null.

armorStands is a map that stores the name of the player along with the armor stand that they spawn in. PlayerInfo.getPI(player.getName()).getChamp() is simply a string that represents the name of the champ the player chose. PlayerInfo is my own custom class where I keep player information and stats.

Any ideas or thoughts? Here's the code:

Code:

Player player = (Player) event.getWhoClicked();
     
        if(armorStands.containsKey(player.getName())){
            armorStands.get(player.getName()).remove();
        }
     
        Location loc = player.getLocation();
        loc.setDirection(loc.getDirection());
        ArmorStand stand = player.getLocation().getWorld().spawn(loc, ArmorStand.class);
        stand.setBasePlate(false);         
        armorStands.put(player.getName(), stand);
     
        armorStands.get(player).setCustomName(PlayerInfo.getPI(player.getName()).getChamp());
        armorStands.get(player).setCustomNameVisible(true);
     
        ItemStack head = new ItemStack(Material.SKULL_ITEM, 1, (short)SkullType.PLAYER.ordinal());
        SkullMeta meta = (SkullMeta) head.getItemMeta();
        meta.setOwner(event.getWhoClicked().getName());
        head.setItemMeta(meta);
        armorStands.get(event.getWhoClicked().getName()).setHelmet(head);
