Attemp to call a nil value (field ‘ShowInventory’) [ESX2]

Question

I just installed ESX 2 into my new server, im Really new at lua and i dont really know what i should do with some resources or how to start coding

I wan to work in the inventory system based on es_extended, but, it doesnt work.

I press the Inventory Key informed in the cofig file \server-data\resources\es_extended\config\default\config.lua

“Config.InventoryKey = “REPLAY_START_STOP_RECORDING_SECONDARY” – Key F2 by default”

module.InitESX = function()
  module.RegisterControl(module.Groups.MOVE, module.Controls[Config.InventoryKey])
  module.On('released', module.Groups.MOVE, module.Controls[Config.InventoryKey], function(lastPressed)
    print("Comment before show The Inventory")
    ESX.ShowInventory()
    -- if Menu.IsOpen ~= nil then
        --  if (not ESX.IsDead) and (not Menu.IsOpen('default', 'es_extended', 'inventory')) then
        --    ESX.ShowInventory()
        --  end 
        -- end
  end)
end

I literally change a little bit the code to directly execute the ShowInventory() Function but i got this error

the original code look like this

module.InitESX = function()
  module.RegisterControl(module.Groups.MOVE, module.Controls[Config.InventoryKey])
  module.On('released', module.Groups.MOVE, module.Controls[Config.InventoryKey], function(lastPressed)
    if Menu.IsOpen ~= nil then
            if (not ESX.IsDead) and (not Menu.IsOpen('default', 'es_extended', 'inventory')) then
              ESX.ShowInventory()
            end 
        end
  end)
end

but when i press the key dont do nothing and doesnt show anything in the console.
