m_hAPICall is Invalid (SteamAPICall_t CreateItem( AppId_t nConsumerAppId, EWorkshopFileType eFileType );)

[JamesMcGhee]

We have a user who is getting m_hAPICall is invalid when attempting to create a UGC item. This was working recently; we have quite a few users using it.

I have tested it myself, including using the raw Steamworks.NET wrapper across a few different versions of the wrapper ... so I assume this may be a Steamworks SDK / Valve issue?

But wanted to raise it here to see if others have ran into this

Thank you @JamesMcGhee for initialising the discussion. I have tested UGC (CreateNewItem) on my Unity Project and I can give the following extra info based on some Debug.Logs in Heathen's API wrapper:

         public void Set(SteamAPICall_t hAPICall, APIDispatchDelegate func = null)
        {
            // Unlike the official SDK we let the user assign a single function during creation,
            // and allow them to skip having to do so every time that they call .Set()
            if (func != null)
            {
                m_Func = func;
            }

            if (m_Func == null)
            {
                throw new Exception("CallResult function was null, you must either set it in the CallResult Constructor or via Set()");
            }

            if (m_hAPICall != SteamAPICall_t.Invalid)
            {
                UnityEngine.Debug.Log($"Unregister…");
                CallbackDispatcher.Unregister(m_hAPICall, this);
            }
            else
            {
                UnityEngine.Debug.Log($"A: m_hAPICall is Invalid"); // This is where I get 'm_hAPICall = INVALID'
            }

            m_hAPICall = hAPICall;

            if (hAPICall != SteamAPICall_t.Invalid)
            {
                UnityEngine.Debug.Log($"Register next…"); // This here is where it nevertheless enters the ' CallbackDispatcher.Register'
                CallbackDispatcher.Register(hAPICall, this);
            }
            else
            {
                UnityEngine.Debug.Log($"B: hAPICall is Invalid");
            }
        }

Inside the CallbackDispatcher.Register I get no errors. As I test like shown below:

         internal static void Register(SteamAPICall_t asyncCall, CallResult cr)
        {
            if (cr == null)
            {
                UnityEngine.Debug.LogError("[CallResult Register] CallResult is NULL");
                return;
            }

            ulong callKey = (ulong)asyncCall;

            if (callKey == 0)
            {
                UnityEngine.Debug.LogError("[CallResult Register] asyncCall is INVALID (0)");
                return;
            }

            if (m_registeredCallResults == null)
            {
                UnityEngine.Debug.LogError("[CallResult Register] Registry dictionary is NULL");
                return;
            }

            lock (m_sync)
            {
                try
                {
                    if (!m_registeredCallResults.TryGetValue(callKey, out var callResultsList))
                    {
                        callResultsList = new List<CallResult>();
                        m_registeredCallResults.Add(callKey, callResultsList);

                        UnityEngine.Debug.Log(
                            $"[CallResult Register] Created new CallResult list for asyncCall {callKey}");
                    }

                    callResultsList.Add(cr);

                    UnityEngine.Debug.Log(
                        $"[CallResult Register] Registered CallResult {cr.GetType().Name} for asyncCall {callKey}");
                }
                catch (Exception e)
                {
                    UnityEngine.Debug.LogError(
                        $"[CallResult Register] Exception while registering asyncCall {callKey}\n{e}");
                }
            }
        }

It returns me both:

[CallResult Register] Created new CallResult list for asyncCall 1366667520 and
[CallResult Register] Registered CallResult CallResult1 for asyncCall 1366667520`

Nevertheless, the callback named OnCreateItem never fires anything (neither result nor error):

      public void StartUpload()
    {
        Debug.Log("[UGC DEBUG]: Initialize creation of an UGC item");
        UGCClient.CreateItem(AppData.Me, EWorkshopFileType.k_EWorkshopFileTypeCommunity, OnCreateItem);
    }

// HERE IS THE PROBLEM >>>>> THIS NEVER FIRES
    private void OnCreateItem(CreateItemResult_t result, bool ioError)
    {
        Debug.Log($"[UGC DEBUG] CreateItem | IO Error: {ioError} | Result: {result.m_eResult}");

        if (ioError || result.m_eResult != EResult.k_EResultOK)
        {
            Debug.LogError("[UGC DEBUG]: Failed to create Workshop item");
            return;
        }

        fileId = result.m_nPublishedFileId;
        Debug.Log($"[UGC DEBUG]: File created: {fileId.m_PublishedFileId}");

        UpdateTitle();
    }

My tests ran today do seem to work as expected
I have testing

Steamwroks.NET directly
Steamworks SDK in C++
and our own tools all working as expected ... today

That said I have a new report from another user about GetWebAuthSessionTicket not raising its callback
