null: Segfault

Saw this one on Sentry today, quite an obscure one with not much data nor stacktrace to help 😒 … but seems the events are still steadily happening and building up since 17.7, so figured it could be worth tracking and checking.

It is hard to reproduce issue. Need to monitor and investigate further.

Most likely suspect is a null pointer dereference. Possibly in parsing a Gson somewhere using Java classes

Not sure if the original issue was related to the Sentry library but I recently noticed that the stacktrace references the method sentry_get_modules_list which is defined by Sentry.

I looked for opened/closed issues on the Sentry repository (getsentry/sentry-java) that might be related and found this one with a similar problem. It states that the crash was addressed in version 5.1.0 by bumping sentry-native to 0.4.12. The current Sentry version defined in Automattic-Tracks-Android is 5.0.1, so I'm wondering if bumping Sentry to version 5.1.0 or newer might help.

I see a reference to Hermes (facebook::hermes::detail::hermesFatalErrorHandler) in a recent Sentry event, so potentially this crash could be related to React Native library. It might be a coincidence but, the first event was originated in version 17.7 which is also the one where the React Native upgrade to version 0.64 was released 🤔 .

FYI: It seems that this event has been spiking for the past 3 months. Maybe it is worth to investigate it again as part of groundskeeping, wdyt? 🤔

@thehenrybyrd Following up on the internal discussion (↗️ ref: pbArwn-52u-p2#comment-6335) we can see in the graph of the past 3 months that the Sentry event has indeed started to show a recent downturn, therefore we might consider re-evaluating its priority in the near future 👍 .

Thanks for following up on this and giving an update @ovitrif! As we're seeing a significant decrease, I'll lower the priority on this one to low.

The issue exists since version 17.7 and the crash rate remains low

This occurred 20 times on May 26 and became one of the top crashes.

Checking the events I think they are all from the same user running WordPress 19.2 on a SM-S908B
device with Android 14 :(
