Fireworks kick Players because of NBT Error

So, I have this random firework generator, and it kicks people for an NBT error. I know it is because of the below code. But I do not see where I am going wrong. If anybody could help, that would be fantastic.

Code:

public void spawnFirework(Player p){
        Firework fw = (Firework) p.getWorld().spawnEntity(p.getLocation(), EntityType.FIREWORK);
        FireworkMeta fwm = fw.getFireworkMeta();
     
     
        Random r = new Random();

      
        int rt = r.nextInt(4) + 1;
        Type type = Type.BALL;    
        if (rt == 1) type = Type.BALL;
        if (rt == 2) type = Type.BALL_LARGE;
        if (rt == 3) type = Type.BURST;
        if (rt == 4) type = Type.CREEPER;
        if (rt == 5) type = Type.STAR;
     
     
        int r1i = r.nextInt(17) + 1;
        int r2i = r.nextInt(17) + 1;
        Color c1 = getColor(r1i);
        Color c2 = getColor(r2i);
     
        //Create our effect with this
        FireworkEffect effect = FireworkEffect.builder().flicker(r.nextBoolean()).withColor(c1).withFade(c2).with(type).trail(r.nextBoolean()).build();
     
    
        fwm.addEffect(effect);
     
    
        int rp = r.nextInt(2) + 1;
        fwm.setPower(rp);
     

        fw.setFireworkMeta(fwm);        
      
      
    }

 

@AppleBabies
Can we see the error?

 

@Zombie_Striker There's no console error: Just a error for the player io.ionetty.NBTHandler or something like that.

 

@AppleBabies
"Something like that" doesn't really help. If it's not in the console, then post what the error is in the IDE.

 

@AppleBabies

Code:

        int rt = r.nextInt(4) + 1;
        Type type = Type.BALL;   
        if (rt == 1) type = Type.BALL;
        if (rt == 2) type = Type.BALL_LARGE;
        if (rt == 3) type = Type.BURST;
        if (rt == 4) type = Type.CREEPER;
        if (rt == 5) type = Type.STAR;

I just want to point out that rt will never be 5 in this case.

 

It's not an IDE error. You can check Minecraft's console but I don't think you'd want to decipher through all that obfuscated garbally-goop.

@AppleBabies Unless you can actually see what the error is from MC's console, I would comment out lines to see if the problem stops.

 

@teej107 I have looked into NBT handling more. This is a very rare thing that happens to players, and it's Minecraft basically saying that it doesn't support a certain feature of the firework. But, then wouldn't EVERYBODY be kicked? I am actually starting to believe that it's not the firework causing the problem.

Could it be this?

Code:

ItemStack fwStack = new ItemStack(Material.FIREWORK);
    ItemMeta fwMeta = fwStack.getItemMeta();
   
    public void configureGadgets(){
        fwMeta.setDisplayName(ChatColor.AQUA + "Fireworks");
        fwMeta.setLore(Arrays.asList(ChatColor.RED + "Cool Fireworks."));
        fwStack.setItemMeta(fwMeta);
    }

 

@AppleBabies I doubt it but

 

@AppleBabies

Everyone who saw it.

But you still haven't posted that error.

 

@AppleBabies show your getColor(int) method?

Switch statement too strong

Code:

       int rt = r.nextInt(4) + 1;
        Type type = Type.BALL;  
       if (rt == 1) type = Type.BALL;
       if (rt == 2) type = Type.BALL_LARGE;
       if (rt == 3) type = Type.BURST;
       if (rt == 4) type = Type.CREEPER;
       if (rt == 5) type = Type.STAR

Why store these?

Code:

       int r1i = r.nextInt(17) + 1;
       int r2i = r.nextInt(17) + 1;
       Color c1 = getColor(r1i);
       Color c2 = getColor(r2i);
