Solved IllegalArgumentException: Invalid inventory size; expected 9 or less

https://hastebin.com/pezeqecodu.css

Code (Text):

List<ItemStack> listitems = new ArrayList<>();

    for (String s : getConfig().getConfigurationSection("Common.Items").getKeys(false)) {
        listitems.add(getConfig().getItemStack("Common.Items." + s + ".item"));
    }
    ItemStack[] array = listitems.toArray(new ItemStack[listitems.size()]);

    InvCLickAdmin.getInstance().invC.setContents(array);
 

 

Ok there was extra stuff in config which was messing it up!

When I reload the inventory is just full of glass
