Showing SignGUI to user raises error

I'm creating a SkyblockCore plugin, which has a function that allows a player (with an island) to invite other players to their island. I'm trying to create a button in a GUI that triggers a SignGUI (which required ProtocolLib), where you can input the name of the player you want to invite to your island! But instead, it showed a "CancelledPacketHandleException"
Full Error:
Unhandled exception occured in onPacketReceiving(PacketEvent) for IronHavenSB net.minecraft.server.v1_16_R3.CancelledPacketHandleException: null [10:15:09] [Netty Server IO #1/ERROR]: Parameters: net.minecraft.server.v1_16_R3.PacketPlayInUpdateSign@13984347[ a=BlockPosition{x=-1, y=76, z=2} b={4MC,,,} ]

API Methods:
VaultAPI
WorldEdit
SpigotAPI
ProtocolLib

I thought it was going to show the SignGUI to a player, where they can type an online player's name, then show a GUI to the player inputted.

InviteIsland class:

`public class InviteIsland {

public InviteIsland(Player p, Main plugin) {

	plugin.signMenuFactory
	.newMenu(Lists.newArrayList("", "", "", ""))
	.reopenIfFail()
	.response((player, lines) -> {
		if (lines[0] != null) {
			
			if (Bukkit.getPlayer(lines[0]) == null) {
				
				p.sendMessage(ChatColor.RED+"[Iron Haven] >> This player is not online!");
				
			} else {
				
				new InviteGUI(Bukkit.getPlayer(lines[0]), p, plugin);
				
			}
			
			return true;

		}
		return false; // failure. becaues reopenIfFail was called, menu will reopen when closed.
	})
	.open(p);

}

}`

InviteGUI class:

`public class InviteGUI {

public static Player invitor;

public InviteGUI(Player victim, Player Invitor, Main plugin) {
	
	invitor = Invitor;
	
	Inventory coopGUI = Bukkit.getServer().createInventory(Invitor, 9, "Accept Island Invite");
	
	// Info Item
	
	ItemStack info = new ItemStack(Material.WITHER_SKELETON_SKULL);
	ItemMeta infoMeta = info.getItemMeta();
	ArrayList<String> infoLore = new ArrayList<String>();
		
	infoLore.add(ChatColor.GREEN+Invitor.getName()+" has invited you to join their coop!");
	
	infoMeta.setLore(infoLore);
	infoMeta.setDisplayName("§6§lInfo");
	
	
	info.setItemMeta(infoMeta);
	coopGUI.setItem(4, info);
	
	// Accept Item
	
	ItemStack acceptItem = new ItemStack(Material.GREEN_CONCRETE);
	ItemMeta acceptItemMeta = acceptItem.getItemMeta();
	ArrayList<String> acceptItemLore = new ArrayList<String>();
	
	acceptItemLore.add(ChatColor.GREEN+"Accept coop invitation!");
	
	acceptItemMeta.setLore(acceptItemLore);
	acceptItemMeta.setDisplayName("§a§lAccept");
	
	acceptItem.setItemMeta(acceptItemMeta);
	coopGUI.setItem(2, acceptItem);
	
	// Decline Item
	ItemStack declineItem = new ItemStack(Material.RED_CONCRETE);
	ItemMeta declineItemMeta = declineItem.getItemMeta();
	ArrayList<String> declineItemLore = new ArrayList<String>();

	declineItemLore.add(ChatColor.RED+"Decline coop invitation!");

	declineItemMeta.setLore(declineItemLore);
	declineItemMeta.setDisplayName("§c§lDecline");

	declineItem.setItemMeta(declineItemMeta);
	coopGUI.setItem(6, declineItem);
	
	//Here opens the inventory
	victim.openInventory(coopGUI);
	
}

}`

Here is my code when a player presses "Accept" or "Decline":

`e.setCancelled(true);
if ((e.getCurrentItem() == null) || (e.getCurrentItem().getType().equals(Material.AIR))) {
return;
}

if (e.getSlot() == 3 && (e.getCurrentItem().getItemMeta().getDisplayName().equalsIgnoreCase("§a§lAccept"))){

new JoinIsland(p, InviteGUI.invitor);

} else if (e.getSlot() == 5 && (e.getCurrentItem().getItemMeta().getDisplayName().equalsIgnoreCase("§c§lDecline"))){

p.sendMessage(ChatColor.RED+"[Iron Haven] >> You declined the coop invitation!");

}`
But the code doesn't even get to opening the GUI for the victim before showing the error.

I followed this tutorial on SignMenus

Also, IDK why github messed up a few of the code lines, but you should be able to piece them together
