Looks like its related to this bit of code which i think relates to the fireball item

    @EventHandler
    public void onProjectileHit(ProjectileHitEvent event)
    {
        Entity entity = event.getEntity();
        Arrow arrow = null;
        if (entity instanceof Arrow)
        {
            arrow = (Arrow)entity;
        }
        if (arrow != null && (arrow.getShooter() instanceof Player))
        {
            if (explosivePlayers.contains((Player)arrow.getShooter()))
            {
                arrow.getLocation().getWorld().createExplosion(arrow.getLocation().getX(), arrow.getLocation().getY(), arrow.getLocation().getZ(), ConfigEntry.EXPLOSIVE_RADIUS.getDouble().floatValue(), false, ConfigEntry.ALLOW_EXPLOSIONS.getBoolean());
                arrow.remove();
            }
        }

        if (entity instanceof Fireball)
        {
            if (FIRE_BALL_UUIDS.contains(entity.getUniqueId()))
            {
                FIRE_BALL_UUIDS.remove(entity.getUniqueId());
                Firework firework = (Firework)entity.getWorld().spawnEntity(entity.getLocation(), EntityType.FIREWORK);
                firework.setSilent(true);
                FireworkMeta meta = firework.getFireworkMeta();
                FireworkEffect explosionEffect = FireworkEffect.builder().withColor(Color.ORANGE).withFade(Color.YELLOW).with(FireworkEffect.Type.BALL_LARGE).trail(true).build();
                meta.addEffect(explosionEffect);
                meta.setPower(0);
                firework.setFireworkMeta(meta);
                entity.remove();
                firework.detonate();
                entity.getWorld().playSound(firework.getLocation(), Sound.ENTITY_GENERIC_EXPLODE, SoundCategory.PLAYERS, 10f, 1f);
            }
        }
    }```

@DragonSlayer2189 The problem is with the arrow part, the explosion is returning null for some reason when it shouldn't.

mabye its checking to see if /explosivearrows is on, and thus returns null if its not?

@VideoGameSmash12 is the error persistent?
