Some questions about making mods

[ikun_01]

I had a few problems making the mod,
Who can help me with the answer?🤔

The first question is: net.minecraft.client.renderer.block.model.ModelBlockDefinition$MissingVariantException

The second question is: java.lang.IllegalArgumentException

The third question is: java.io.FileNotFoundException: itnt:models/item/tnt_ball.json(My ModID is: itnt)

The file path is: zzzz.itnt.itnt.java

package zzzz.itnt;

import net.minecraft.init.Blocks;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;
import org.apache.logging.log4j.Logger;

@Mod(modid = itnt.MODID, name = itnt.NAME, version = itnt.VERSION, acceptedMinecraftVersions = "[1.12,1.13)")
public class itnt
{
    public static final String MODID = "itnt";
    public static final String NAME = "Ikun tnt";
    public static final String VERSION = "1.0";

    private static Logger logger;

    @EventHandler
    public void preInit(FMLPreInitializationEvent event)
    {
        logger = event.getModLog();
    }

    @EventHandler
    public void init(FMLInitializationEvent event)
    {
        // some example code
        logger.info("DIRT BLOCK >> {}", Blocks.DIRT.getRegistryName());
    }
}

The file path is: zzzz.itnt.item.tntBall.java

package zzzz.itnt.item;

import net.minecraft.item.Item;
import zzzz.itnt.itnt;

public class tntBall extends Item {
    public tntBall()
    {
        this.setUnlocalizedName(itnt.MODID+".dirtball");
        this.setRegistryName("dirt_ball");
        this.setMaxStackSize(16);
    }
}

The file path is: zzzz.itnt.item.ItemRegistryHandler.java

package zzzz.itnt.item;

import net.minecraft.client.renderer.block.model.ModelResourceLocation;
import net.minecraft.item.Item;
import net.minecraftforge.client.event.ModelRegistryEvent;
import net.minecraftforge.client.model.ModelLoader;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.event.RegistryEvent.Register;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;
import net.minecraftforge.registries.IForgeRegistry;

@Mod.EventBusSubscriber
public class ItemRegistryHandler
{
    public static final tntBall TNT_BALL = new tntBall();

    @SubscribeEvent
    public static void onRegistry(Register<Item> event)
    {
        IForgeRegistry<Item> registry = event.getRegistry();
        registry.register(TNT_BALL);
    }

    @SubscribeEvent
    @SideOnly(Side.CLIENT)
    public static void onModelRegistery(ModelRegistryEvent event)
    {
        ModelLoader.setCustomModelResourceLocation(TNT_BALL,0,
                new ModelResourceLocation(TNT_BALL.getRegistryName(),"inventory"));
    }
}

And in the resources folder have:

resource\

    assets\

        itnt\

            lang\

                 en_us.lang

                 zh_cn.lang

            models\

                  item\

                          tnt_ball.json

                          (The tnt_ball.json code:

{
    "parent": "item/generated",
    "textures": {
        "layer0": "dirtgy:items/dirtball"
    }
}

)

            textures\

                  items\

                           tnt_ball.png

     mcmod.info

     pack.mcmeta

     (The mcmod.info code:

[
{
  "modid": "Itnt",
  "name": "Ikun tnt",
  "description": "Ikun tnt mod",
  "version": "${version}",
  "mcversion": "${mcversion}",
  "url": "",
  "updateUrl": "",
  "authorList": ["zzzz"],
  "credits": "Ikun tnt, zzzz",
  "logoFile": "",
  "screenshots": [],
  "dependencies": []
}
]

),

(The pack.mcmeta code:

{
    "pack": {
        "pack_format": 3,
        "description": "Ikun tnt resources"
    }
}

)

This is the code I wrote, who can help me to see where the problem?
