OTClient Unable to send extended opcode

[MorganaSacani]

I'm trying to learn how to use extended opcode on my TFS 0.4, but I'm having the following problem:

ERROR: Unable to send extended opcode 56, extended opcodes are not enabled on this server.

File from Otclient:
food_eater.lua:

foodeaterButton = nil
foodeaterWindow = nil

local EAT_OPCODE = 56

function init()
    foodeaterButton = modules.client_topmenu.addRightGameToggleButton('foodeaterButton', tr('Food Eater'), '/images/topbuttons/food_eater', closing, false, 1)
    foodeaterButton:setOn(false)
    foodeaterWindow = g_ui.displayUI('food_eater')
    foodeaterWindow:setVisible(false) 
    
    allTabs = foodeaterWindow:recursiveGetChildById('allTabs')
    allTabs:setContentWidget(foodeaterWindow:getChildById('optionsTabContent'))
end

function terminate()
    foodeaterButton:destroy()
    foodeaterWindow:destroy()
end

function closing()
    if foodeaterButton:isOn() then
        foodeaterWindow:setVisible(false)
        foodeaterButton:setOn(false)
     else
        foodeaterWindow:setVisible(true)
        foodeaterButton:setOn(true)
    end
end

function banana()
    local protocolGame = g_game.getProtocolGame()
    if foodeaterButton:isOn() then
        if protocolGame then
            protocolGame:sendExtendedOpcode(EAT_OPCODE, 1)
        end
    else
        foodeaterWindow:setVisible(true)
        foodeaterButton:setOn(true)
    end
end

function melon()
    local protocolGame = g_game.getProtocolGame()
    if foodeaterButton:isOn() then
        if protocolGame then
            protocolGame:sendExtendedOpcode(EAT_OPCODE, 2)
        end
    else
        foodeaterWindow:setVisible(true)
        foodeaterButton:setOn(true)
    end
end

function cake()
    local protocolGame = g_game.getProtocolGame()
    if foodeaterButton:isOn() then
        if protocolGame then
            protocolGame:sendExtendedOpcode(EAT_OPCODE, 3)
        end
    else
        foodeaterWindow:setVisible(true)
        foodeaterButton:setOn(true)
    end
end

function onMiniWindowClose()
    foodeaterButton:setOn(false)
end

Files from my TFS 0.4:
creaturescripts.xml:

<event type="extendedopcode" name="foodeater" event="script" value="foodeater.lua"/>

login.lua:

registerCreatureEvent(cid, "foodeater")

foodeater.lua:

local EAT_OPCODE = 56

function onExtendedOpcode(cid, opcode, buffer)
    local banana = getPlayerItemCount(cid, 2676)
    local cake = getPlayerItemCount(cid, 6278)
    local melon = getPlayerItemCount(cid, 2680)
    local buf = tonumber(buffer)
    
    if opcode == EAT_OPCODE and buf == 1 and banana >= 1 then
        doCreatureSay(cid, "Omn, omn~! Banani!", TALKTYPE_MONSTER_SAY)
        doPlayerRemoveItem(cid, 2676, 1)
    elseif opcode == EAT_OPCODE and buf == 3 and cake >= 1 then
        doCreatureSay(cid, "Omn, omn~! Fat Boosting!", TALKTYPE_MONSTER_SAY)
        doPlayerRemoveItem(cid, 6278, 1)
    elseif opcode == EAT_OPCODE and buf == 2 and melon >= 1 then
        doCreatureSay(cid, "Omn, omn~! He?!", TALKTYPE_MONSTER_SAY)
        doPlayerRemoveItem(cid, 2680, 1)
    end
    return true
end

I've solved in features.lua with:

g_game.enableFeature(GameExtendedOpcode)
