Basically when I try using version 3.4.0 or 3.5.0 on paper 1.21.6

I will receive following error message:

✔️ Expected behavior

The inventory should open as usual

👣 Steps to Reproduce

use the anvilinput example of the repository, in an paper environment newest version of paper 1.21.6 and either IF 3.4.0 or 3.5.0 both causing issues.

💻 Platform

• Bukkit
• Sponge
• Other

⭐ Server Version

1.21.6

📚 Library Version

3.4.0, 3.5.0

✍️ Additional context

package de.jexcellence.currency.view.currency;

import me.devnatan.inventoryframework.AnvilInput;
import me.devnatan.inventoryframework.View;
import me.devnatan.inventoryframework.ViewConfigBuilder;
import me.devnatan.inventoryframework.ViewType;
import me.devnatan.inventoryframework.context.RenderContext;
import org.bukkit.Material;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
import org.jetbrains.annotations.NotNull;

public class AnvilInputSample extends View {

final AnvilInput anvilInput = AnvilInput.createAnvilInput();

@Override
public void onInit(@NotNull ViewConfigBuilder config) {
    config.cancelOnClick();
    config.type(ViewType.ANVIL);
    config.title("Anvil Input Sample");
    config.use(anvilInput);
}

@Override
public void onFirstRender(@NotNull RenderContext render) {
    ItemStack itemStack = new ItemStack(Material.DIAMOND);
    ItemMeta itemMeta = itemStack.getItemMeta();
    itemMeta.setDisplayName("Type something here");
    itemStack.setItemMeta(itemMeta);

    render.firstSlot(itemStack);

    render.resultSlot().onClick((ctx) -> {
        ctx.getPlayer().sendMessage("You typed: " + anvilInput.get(ctx));
    });
}

}

this is how my class looks like and how i registered the classes
this.viewFrame = ViewFrame
.create(this)
.install(AnvilInputFeature.AnvilInput)
.defaultConfig(config -> {
config.cancelOnClick();
config.cancelOnDrag();
config.cancelOnDrop();
config.cancelOnPickup();
config.interactionDelay(Duration.ofMillis(100));
})
.with(
new CurrenciesCreatingView(),
new CurrenciesActionOverviewView(),
new CurrencyIdentifierAnvilView(),
new CurrencySymbolAnvilView(),
new CurrencyPrefixAnvilView(),
new CurrencySuffixAnvilView(),
new AnvilInputSample()
)
.register();

weird enough that the sample jar you published works fine.

[JExcellence]

final AnvilInventory inventory = (AnvilInventory) ((InventoryView) InventoryUpdate.getBukkitView.invoke(anvilContainer)).getTopInventory();

it keeps failing here no matter what i do, (AnvilInputNMS.java line 96)

[JExcellence]

Fixed the bug by having a workaround...

Basically the issue is that inside of the Example Jar in line 96 there is no (InventoryView) for parsing used.. if we remove that, we dont have any further issues with opening a anvil gui @devnatan if you want i can create a pullrequest for it..

@JExcellence Please create a PR as I am experiencing the same issue

[JExcellence]

@CrazyDev05 give me some time to add it, otherwise I can send you the classes locally through discord to you if you like. Shouldn't be that hard to implement it. 👍

I made a PR fixing it myself an hour after my message but messed up the issue id🙈
but I'm still interested in your solution

[JExcellence]

So basically I re-wrote these files.. overwriting some of Inventory Framework where it was possible for me to use the fixed version.. since I couldn't wait longer to actually get it done. 💯
