Hello, today I was trying to add new inventory slots for my server, server side everything seems to be working correctly, but with the client its a complete different story.

Getting this on my log and console in the client.
Lua: 
ERROR: Lua exception: /game_inventory/inventory.lua:2: table index is nil
stack traceback:
    [C]: in function '__newindex'
    /game_inventory/inventory.lua:2: in main chunk
    [C]: in function 'ensureModuleLoaded'
    /init.lua:59: in main chunk
ERROR: Unable to load module 'game_inventory': LUA ERROR:
/game_inventory/inventory.lua:2: table index is nil

    [C]: in function '__newindex'
    /game_inventory/inventory.lua:2: in main chunk
    [C]: in function 'ensureModuleLoaded'
    /init.lua:59: in main chunk

This is my inventory.lua:

Lua: 
InventorySlotStyles = {
    [InventorySlotNecklaceLeft] = 'NeckSlotLeft',
    [InventorySlotHead] = 'HeadSlot',
    [InventorySlotNecklaceRight] = 'NeckSlotRight',
    [InventorySlotLeft] = 'LeftSlot',
    [InventorySlotBody] = 'BodySlot',
    [InventorySlotRight] = 'RightSlot',
    [InventorySlotRingLeft] = 'RingSlotLeft',
    [InventorySlotLegs] = 'LegSlot',
    [InventorySlotRingRight] = 'RingSlotRight',
    [InventorySlotTrinket] = 'TrinketSlot',
    [InventorySlotFeet] = 'FeetSlot',
    [InventorySlotAmmo] = 'AmmoSlot',
    [InventorySlotBackpack] = 'BackSlotOne',
    [InventorySlotBackpackTwo] = 'BackSlotTwo',
    [InventorySlotBackpackThree] = 'BackSlotThree',
    [InventorySlotBackpackFour] = 'BackSlotFour',
    [InventorySlotBackpackFive] = 'BackSlotFive',
    [InventorySlotBackpackSix] = 'BackSlotSix'
}

    })


    g_keyboard.bindKeyDown('Ctrl+I', toggle)


    inventoryButton = modules.client_topmenu.addRightGameToggleButton('inventoryButton', tr('Inventory') .. ' (Ctrl+I)',
                                                                      '/images/topbuttons/inventory', toggle)

    })
    disconnect(g_game, {

    })


    g_keyboard.unbindKeyDown('Ctrl+I')


    inventoryWindow:destroy()
    inventoryButton:destroy()


    inventoryWindow = nil

end


function toggleAdventurerStyle(hasBlessing)

    end
end

    refresh()
end


function offline()
    inventoryWindow:setParent(nil, true)
end


function refresh()
    local player = g_game.getLocalPlayer()
    for i = InventorySlotFirst, InventorySlotPurse do
        if g_game.isOnline() then
            onInventoryChange(player, i, player:getInventoryItem(i))
        else
            onInventoryChange(player, i, nil)
        end
        toggleAdventurerStyle(player and Bit.hasBit(player:getBlessings(), Blessings.Adventurer) or false)
    end


    purseButton:setVisible(g_game.getFeature(GamePurseSlot))
end


function toggle()
    if inventoryButton:isOn() then
        inventoryWindow:close()
        inventoryButton:setOn(false)
    else
        inventoryWindow:open()
        inventoryButton:setOn(true)
    end
end

end


-- hooked events
function onInventoryChange(player, slot, item, oldItem)
    if slot > InventorySlotPurse then
        return
    end


    if slot == InventorySlotPurse then
        if g_game.getFeature(GamePurseSlot) then
            purseButton:setEnabled(item and true or false)
        end
        return
    end


    local itemWidget = inventoryPanel:getChildById('slot' .. slot)
    if item then
        itemWidget:setStyle('InventoryItem')
        itemWidget:setItem(item)
    else
        itemWidget:setStyle(InventorySlotStyles[slot])
        itemWidget:setItem(nil)
    end
end


function onBlessingsChange(player, blessings, oldBlessings)
    local hasAdventurerBlessing = Bit.hasBit(blessings, Blessings.Adventurer)
    if hasAdventurerBlessing ~= Bit.hasBit(oldBlessings, Blessings.Adventurer) then
        toggleAdventurerStyle(hasAdventurerBlessing)
    end
end

And this would be my inventory.otui

Found solution, for some reason, some of the declarations of inventory slots in gamelib/player.lua were incorrect, also had to get rid of the purse don't know what was going on there.
