Attachments in sentry subsystem ConfigureScope fail to upload

[adamboerema]

Environment

How do you use Sentry?
Sentry SaaS

Which version of the SDK?
0.2.0

How did you install the package? (Git-URL, Assetstore)
Manually included Sentry Unreal Plugin in project

Which version of Unreal?
4.27.2

Is this happening in Unreal (editor) or on a player like Android, iOS, Windows?
Android

Steps to Reproduce

Configured custom attachments on the ConfigureScope callback in the GameInstance Init method. Local logs show the file being found and attached but on Sentry the log is not included in the crash event attachments. However, manually calling ConfigureEventWithScope or ConfigureMessageWithScope properly includes the attachment with the same delegate.

I've also tried this in blueprints using your documentation with no success either.

Expected Result

I would expect to see the attachment included in the crash event.

Actual Result

No attachment is included in the crash event.

Code sample:

void UCustomLoggingManager::ConfigureScope()
{
	FConfigureScopeDelegate Delegate;
	Delegate.BindDynamic(this, &UCustomLoggingManager::HandleScope);
	SentrySubsystem->ConfigureScope(Delegate);
}

void UCustomLoggingManager::HandleScope(USentryScope* Scope)
{
	if(!Scope) return;

	const FString FilePath = FPaths::Combine(FPaths::ProjectLogDir(), TEXT("client.log"));
	const FString SentryFileName(TEXT("client.log"));
	
	USentryAttachment* PathAttachment = NewObject<USentryAttachment>();
	PathAttachment->InitializeWithPath(FilePath, SentryFileName);
	Scope->AddAttachment(PathAttachment);
}

Thanks for reporting this. I'll try to reproduce this locally.

Unfortunately, I don't know how to phrase this in a more favorable light but currently, this is a known limitation of the native SDK.
I'll change this from a bug to a feature request.

Relates to:

After revisiting this issue, it appears that adding attachments to crash events via the global scope is still limited by the SDK which Unreal plugin uses internally on Android. The only solution at this point is to configure a custom beforeSend handler and add the attachments on the next app launch by using a hint object.

This could be also related to:

• Is there a callback when native crash happens? sentry-java#1615
• Capture logcat output as attachment sentry-java#3075

Yes, today if you set an attachment in Java/Kotlin, it doesn't end up on NDK crashes. Any SDK built on top of our Android SDK has that behavior. @romtsn @markushi are there plans to change/improve this? @limbonaut was looking at this for Godot too, and @bitsandfoxes for Unity so we could all benefit from collaborating here
