Exception during editor shutdown

[EAron1]

During closing editor GameKit throws exception (UE_DEBUG_BREAK()) on PureCallHandler() every time!

Hi EAron1, thanks for reporting this issue.

Would you mind providing the following information to help us reproduce the issue?

Development Environment

• AWS GameKit Version [e.g. 1.1]
• Unreal Editor Version [e.g. 4.27.2]
• IDE and Version [e.g. Visual Studio 2019 16.11.7]
• OS & Version: [e.g. Windows 11 or Mac 12.5]

Logs If possible, any output logs leading up to the crash.

Steps to Reproduce

• Are there any specific steps you need to take before closing the editor in order for this exception to be thrown?
• Does the exception depend on any of these?
  • whether you've opened the Project Settings window during the Unreal session
  • whether you've added a GameKit sample object to the World Outliner? (e.g. BP_AwsGameKitGameSavingExamples or AwsGameKitAchievementsExamples)
  • whether you've submitted your AWS Credentials to the AWS GameKit Plugin Settings

[EAron1]

Sure. AWS GameKit version is 1.1. Unreal is 4.27.2 VS is 2019 v16.11.2 OS Windows 10

I'm attaching a Log cropped from the moment when the map is loaded (on startup) to shutting down. AWS GK log.txt

No specific steps, just open and close the editor with the GameKit plugin enabled and credentials submitted. With and without Project Settings opened crash happens. No, I haven't added GameKit sample objects, I coded my own logic in blueprints using GameKit functions. Yes. If credentials aren't submitted, the crash doesn't happen.

I've tried to reproduce with a new project but couldn't get crash. The crash happens on two separate projects already in development for a longer time and one prototype project created only for AWS features (GameLift & GameKit). I also tried reinstalling the plugin from the projects but crash still happens after reinstallation.

I found out in AwsGameKitRuntime.cpp under ShutdownModule() method comment " // Calling Shutdown() on this module gives exceptions after the editor is closed.", which might be what happens here and indicate you're already familiar with the issue?

Thank you for the quick answer and let me know if you need any more info, I'll be happy to provide it.

Hi EAron1,

I have created a ticket to track the issue of unwanted exception. I wanted to get a better sense of the issue at hand. Are you experiencing a crash or you just see the exception. It is my understanding that the exception is benign but I would like to know your experience and the impact it is having on your work.

Thanks.

Okay. It's hard to tell because it's on shutdown, as from what I understand exception is thrown at UE_DEBUG_BREAK() which closes the editor in case of issues. It doesn't seem like a huge issue, but definitely, it's not normal behavior. Besides a mild annoyance during every shutdown, my only concern is it might not clean up everything it should during the shutdown. Currently, I didn't experience any issues with product development so it's not crucial for our future development. I just thought you should be aware of the issue.
