App crashes when using Jitsi with Hermes enabled

[Abhishek-Khanduri]

Description:

In my React Native application with Hermes enabled, the app crashes when a user joins the room or when more than two users join the room. I fixed this issue by disabling Hermes, but now it crashes on some Android 10 devices.

Expected behavior:

The app should work with Hermes enabled.

Actual behavior:

The app crashes when Hermes is enabled and a user joins a room, or when more than two users join a room.

Server information:

• Jitsi Meet sdk: ^2.2.1
• RN version :- 0.71.0

Client information:

• Browser / app version: Android 10(when hermes is disabled) For all android devices(when hermes is enable)
• Operating System: Android

Additional information:

This is the error trace I get when I enable hermes and run the app in release mode, on Android Studio when I check the Android logs

This is the error trace I'm encountering on some Android 10 devices after disabling Hermes to use Jitsi.

The last error suggests you haven't disabled Hermes properly since it's still looking for it.

[Abhishek-Khanduri]

@saghul Yes, that's the catch. It's working fine for most users after disabling Hermes. However, for some Android 10 devices, the error trace mentioned above is being logged on Crashlytics.
I have also cleaned the Gradle before creating the bundle and also tried this multiple times on the internal testing environment and the same behavior there as well:

This is my app's gradle.properties where I have hermesEnabled=false

Additionally, can't I use Jitsi with Hermes enabled?

[saghul]

I don't know why you see errors related to Hermes if you have disabled it. Sounds like an RN bug.

As for why you can't use it: you can try, but we don't use it so we won't be able to help you when it breaks.

Last we tried things didn't work out well so we keep using JSC.
