Compiling LuaInterface Implamentation Function issue

[Stellow]

int LuaScriptInterface::luaSetPartySharedExperience(lua_State *L)
{
    std::cout << "1" << std::endl;
    //luaSetPartySharedExperience(cid)
   
    //getPartyMembers(cid)
    uint32_t cid = popNumber(L);

    ScriptEnviroment* env = getScriptEnv();

    Creature* creature = env->getCreatureByUID(cid);
    if(!creature){
        reportErrorFunc(getErrorDesc(LUA_ERROR_CREATURE_NOT_FOUND));
        lua_pushboolean(L, false);
        return 1;
    }
    std::cout << "2" << std::endl;

    Player* player = creature->getPlayer();
    if(!player){
        reportErrorFunc(getErrorDesc(LUA_ERROR_PLAYER_NOT_FOUND));
        lua_pushboolean(L, false);
        return 1;
    }

    std::cout << "3" << std::endl;

    if(!player->getParty()){
        lua_pushnil(L);
        return 1;
    }

    std::cout << "4" << std::endl;
    player->getParty()->setSharedExperience(player, true);
    return 1;
}

Its saying:
LuaScriptInterface::LuaSetPartySharedExperience (). Creature not found
