Duplicate Sentry Reports for Native Client Crashes

[Atul767]

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Sentry Saas (sentry.io)

Electron SDK Version

4.22.0

Electron Version

27.2.20

What platform are you using?

None

Link to Sentry event

https://jupiter-ct.sentry.io/issues/5977075889/events/d8cb5ff92ddd4fbb9e7bd0380f77df83/?project=1430058 , https://jupiter-ct.sentry.io/issues/5105499169/events/49718a83fe6142b4a727520fb6ce24d8/?project=4506692758077440

Steps to Reproduce

1. Launch the Native Client from the parent application
2. Trigger a crash in the Native Client.
3. Observe the crash being reported in both Sentry projects (one under the parent application, one under the Native Client).

We have observed an issue where the same crash is being reported in two separate Sentry projects:

The parent application's Sentry project (e.g., Jupiter).
The Native Client's Sentry project.
This duplication occurs when the Native Client is launched from the parent application. Both projects log the same crash as separate issues.

Example:
Here are two examples of duplicate issues for the same crash:

Parent Application Sentry Project: [MTKView draw]: Fatal Error: EXC_BREAKPOINT / EXC_ARM_BREAKPOINT / 0x100742e00 — Project: jupiter-ct.
Native Client Sentry Project: EXC_BREAKPOINT: height — Project: ringcentral-video-nc.

Expected Result

• Prevent the parent application from sending Sentry reports for crashes that originate in the Native Client.
• Ensure that Native Client crashes are reported only in the Native Client's Sentry project

Actual Result

This duplication occurs when the Native Client is launched from the parent application. Both projects log the same crash as separate issues.

So the parent app is the Electron app, or the native app? Is the native app using the Sentry Native SDK?

Does this only occur on macOS or all platforms?

Hi @timfish ,

So the parent app is the Electron app, or the native app?
Answer: The parent app is the Electron app.

Is the native app using the Sentry Native SDK?
Answer: Yes,

Does this only occur on macOS or all platforms?
Answer: Based on the Sentry logs, I am currently seeing this issue on macOS devices. I’m not yet certain about other platforms.

The Sentry Electron SDK uses the Electron crashReporter API to capture native crashes and it states:

Note that if the crash reporter is started in the main process, it will automatically monitor child processes

There's no option to configure it so I don't think there's anything we can do to stop this. You may be able to custom build Electron and disable this but that would be a lot of work.

When starting your native code from Electron, you could set an environment variable that your native uses to disable crash handling?

Hi @timfish, If we call process.crashReporter.addExtraParameter('ignore', 'true') in the child_process and then filter out such crashes in beforeSend hook, would this approach be feasible? Additionally, I’m concerned that even if we manage to filter out these events from being uploaded, would it still impact the parent project’s Crash Free Session Rate?
