getCreatureStorage returning NIL

[Way20]

On my server when the player doens't have the storage, instead of returning -1 its returning nil, so if I use

math.max(0, getCreatureStorage(cid, storage))

I got this error.

bad argument #3 to 'max' (number expected, got nil)

I think that is source related, can anyone give me a hint to where I should look?

i guess this function could solve it but

function getStore(cid,storage)
  return getCreatureStorage(cid,storage) or -1
end

else i guess check luascript.cpp or creature.cpp

I already made a function similar but I wanna fix it through source editing. And I already looked in luascript and creature.cpp.

Luascript.cpp

int32_t LuaInterface::luaGetCreatureStorage(lua_State* L)
{
    //getCreatureStorage(cid, key)
    std::string key = popString(L);
    ScriptEnviroment* env = getEnv();
    if(Creature* creature = env->getCreatureByUID(popNumber(L)))
    {
        std::string strValue;
        if(!creature->getStorage(key, strValue))
        {
            lua_pushnumber(L, -1);
            lua_pushnil(L);
            return 2;
        }

        int32_t intValue = atoi(strValue.c_str());
        if(intValue || strValue == "0")
            lua_pushnumber(L, intValue);
        else
            lua_pushstring(L, strValue.c_str());
    }
    else
    {
        errorEx(getError(LUA_ERROR_CREATURE_NOT_FOUND));
        lua_pushboolean(L, false);
    }

    return 1;
}

Creature.cpp

bool Creature::getStorage(const std::string& key, std::string& value) const
{
    StorageMap::const_iterator it = storageMap.find(key);
    if(it != storageMap.end())
    {
        value = it->second;
        return true;
    }

    value = "-1";
    return false;
}

It seens fine to me, I don't know what else I can do.
