Crash on Steamworks4j-1.9.0 after attempting to use SteamUGC.createItem

[Daburnell112]

Attempting to write a command line tool to upload a mod for a game on the Steam Workshop. The game is not yet purchasable on Steam and has not been approved for release, yet. Part of the approval process is to upload a single mod to the workshop.

This is the code I'm attempting to use:

This is the error that is resulting:

That's an odd place for a crash. Note that even for command-line tools, you still need to do the full init()/runCallback()/shutdown() cycle. For example, this is how it looks like in our tool:

        SteamAPI.init();
        SteamAPI.printDebugInfo(System.out);

        ugc = new SteamUGC(ugcCallback);

        utils = new SteamUtils(utilsCallback);
        utils.setWarningMessageHook((severity, message) -> LOG.warn("({}) {}", severity, message));

        if (config.publishedFileID == 0) {
            // kick off the item creation process
            ugc.createItem(CONSUMER_APPID, WorkshopFileType.Community);
        } else {
            // update an existing item
            submitItemUpdate(new SteamPublishedFileID(config.publishedFileID), true);
        }

        while (!DONE) {
            SteamAPI.runCallbacks();
            try {
                Threads.sleep(250, 0);
            } catch (InterruptedException e) {
                throw new SteamException(e);
            }
        }

        ugc.dispose();
        utils.dispose();

        SteamAPI.shutdown();

Any more logic is done inside the callbacks, and that DONE flag is raised at the end of everything.

i might have the exact same issue ... has this ever been sorted out?

this is from my console output:

when calling the api like so (please excuse the messy code!! i'm in the fiddling around phase of it...)
