TFS 1.X+ getDirection() of target - TFS1.3

[GOD Half]

Hi guys, how do I print the direction the target is looking?
The model below prints the direction the player is looking, but I need the direction that the target of the player is looking to be printed:

function onThink(interval, lastExecution, thinkInterval)
    for _, player in ipairs(Game.getPlayers()) do
        local dirPlayer = player:getDirection() -- or getPlayerLookDir(player)        -- 0: n | 1: e | 2: s | 3: w
        print("Your direction: "..dirPlayer)
    end
return true
end

I'm trying but from error below:

function onThink(interval, lastExecution, thinkInterval)
    for _, player in ipairs(Game.getPlayers()) do
        local target = getCreatureTarget(player)
        if isPlayer(target) or isMonster(target) then
            local dirTarget = target:getDirection() -- ERROR
            print("Target direction: "..dirTarget)
        end
    end
return true
end

function onThink(interval, lastExecution, thinkInterval)
    for _, player in ipairs(Game.getPlayers()) do
        local target = player:getTarget()
        if target then
            if target:isPlayer() or target:isMonster() then
                local dirTarget = target:getDirection()
                print("Target direction: "..dirTarget)
            end
        end
    end
    return true
end
