Using TFS 1.1 when i kill a monster i get the follow error in consol.

Section specified in console error

local function useStamina(player)
    local staminaMinutes = player:getStamina()
    if staminaMinutes == 0 then
        return
    end

    local playerId = player:getId()
    local currentTime = os.time()
    local timePassed = currentTime - nextUseStaminaTime[playerId]
    if timePassed <= 0 then
        return
    end

    if timePassed > 60 then
        if staminaMinutes > 2 then
            staminaMinutes = staminaMinutes - 2
        else
            staminaMinutes = 0
        end
        nextUseStaminaTime[playerId] = currentTime + 120
    else
        staminaMinutes = staminaMinutes - 1
        nextUseStaminaTime[playerId] = currentTime + 60
    end
    player:setStamina(staminaMinutes)
end

function Player:onGainExperience(source, exp, rawExp)
    if not source or source:isPlayer() then
