Hi guys im making a custom esx thief from the base, I having problem with dragging, when someone click on “drag” the console give me back that error:

but i don’t understand the error, this is the client code:

function OpenCuffMenu()

  local elements = {
        {label = _U('cuff'), value = 'cuff'},
        {label = _U('uncuff'), value = 'uncuff'}, 
        {label = _U('drag'), value = 'drag'},
		{label = _U('search'), value = 'search'}, 
      }

  ESX.UI.Menu.CloseAll()

  ESX.UI.Menu.Open(
    'default', GetCurrentResourceName(), 'cuffing',
    {
      title    = _U('handcuffs'),
      align    = 'top-left',
      elements = elements
      },
          function(data2, menu2)
            local player, distance = ESX.Game.GetClosestPlayer()
            if distance ~= -1 and distance <= 3.0 then
              if data2.current.value == 'cuff' then
                if Config.EnableItems then

                    local target_id = GetPlayerServerId(player)
                
--                    IsAbleToSteal(target_id, function(err)

--                        if not err then
                            ESX.TriggerServerCallback('esx_thief:getItemQ', function(quantity)
                                if quantity >= 0 then
                                    IsAbleToSearch = true
                                    TriggerServerEvent('cuffServer', GetPlayerServerId(player))
                                else

                                end
                            end, 'handcuffs')

                        end
                    else
                        ESX.ShowNotification(_U('not_cuffed'))
                    
                    end
                else
                    ESX.ShowNotification(_U('not_armed'))

            else
              ESX.ShowNotification(_U('no_players_nearby'))
            end
          end,
    function(data2, menu2)
      menu2.close()
    end
  )

end

and this is the server code

RegisterServerEvent('dragServer2')

AddEventHandler('dragServer2', function(target)

  TriggerClientEvent('dragClient2', target, source)

end)

how can i fix it?
