Help with IClientUser::SpawnProcess

[devilExE3]

Hello, I would like to start by saying nice fork, thanks for keeping it up to date.

The issue i'm currently facing is that i can't get IClientUser::SpawnProcess to work for the life of me.

If anyone can please look at my code and tell my what I did wrong, or what I'm missing, please tell me.

    IClientShortcuts* clientShortcuts = m_clientEngine->GetIClientShortcuts(hSteamUser, hSteamPipe);
    uint32_t appId = clientShortcuts->GetUniqueLocalAppId();
    uint32_t parentAppId = 243750;
    uint64_t gameId = 0xD8A9994402000000 | parentAppId; // 'cfx' crc32 + shortcut
    std::cout << "[parent] " << appId << ' ' << parentAppId << ' ' << gameId << std::endl;

    IClientApps* clientApps = m_clientEngine->GetIClientApps(hSteamUser, hSteamPipe);
    KeyValuesBuilder builder;
    builder.PackString("name", "Muck.NET");
    builder.PackUint64("gameid", gameId);
    builder.PackString("installed", "1");
    builder.PackString("gamedir", "cfx");
    builder.PackString("serverbrowsername", "lovely!");
    builder.PackEnd();

    std::string str = builder.GetString();
    bool ok = clientApps->SetLocalAppConfig(appId, (uint8_t*)str.c_str(), str.size());
    if (ok)
    {
        std::cout << "[parent] " << "Config Set OK" << std::endl;
        IClientUtils* clientUtils = m_clientEngine->GetIClientUtils(hSteamPipe);

        // set pipe appid
        clientUtils->SetAppIDForCurrentPipe(parentAppId, false);
        std::cout << "[parent] " << "AppId set for current pipe" << std::endl;

        IClientUser* clientUser = m_clientEngine->GetIClientUser(hSteamUser, hSteamPipe);

        wchar_t directory[MAX_PATH];
        GetCurrentDirectoryW(sizeof(directory), directory);
        std::wstring process(directory);
        process.append(L"\\Test Platform.exe");
        std::wstringstream cmdwss;
        cmdwss << '"' << process << "\" child " << parent_parentPID;
        std::wstring cmd = cmdwss.str();
        
        std::wcout << "[parent] " << directory << std::endl;
        std::wcout << "[parent] " << process.c_str() << std::endl;
        std::wcout << "[parent] " << cmd.c_str() << std::endl;

        std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>, wchar_t> converter;

        if(clientUser->SpawnProcess(converter.to_bytes(process).c_str(), converter.to_bytes(cmd).c_str(), converter.to_bytes(directory).c_str(), &gameId, "Muck.NET", 0, 0, 0))
            std::cout << "[parent] " << "Process Spawned" << std::endl;
        else {
            std::cout << "[parent] " << "SpawnProcess returned false" << std::endl;
        }
    }

This code is mostly copied from the FiveM repository, here

Thanks to anyone reading and trying to help me.

This fork is a bit out of date atm, maybe that's the reason why it doesn't work as expected...

I've managed to get it working by implementing method lookup via name, as the cfx.re team did in their repo.
Also to be noted when i call it with the current signature it returns false, it works when calling with

([thisPtr,] converter.to_bytes(process).c_str(), converter.to_bytes(cmd).c_str(), 0, converter.to_bytes(directory).c_str(), gameId, "Muck.NET", 0, 0)
