[Bug]: App crashes when moved to Background (FATAL EXCEPTION)

[mariusbolik]

What happened?

Hello,

I got some user Feedback, that my capacitor app crashes after login and users can't get logged in. I am sending the ID and email of a user to OneSignal after they have logged in.

Tested with:

• Umidigi One, Android 8.1
• Samsung Galaxy S52, Android 13

Steps to reproduce?

I am using the Capacitor In-App-Browser to perform an Open ID Login Flow. It seems like the In-App-Browser stops the process of the app. After the Browser was opened, the app gets moved to the background and crashes.

I am using Capacitor 5.4.1!

Edit: I see this error everey time I click the home button which moves the app to the background.

What did you expect to happen?

The app should not crash 👀

OneSignal Cordova SDK version

5.0.0

Which platform(s) are affected?

• iOS
• Android

I can't use my Capacitor 5 App with OneSignal. Is there any update on this? @jennantilla

@mariusbolik do you already have any update on this?

[mariusbolik]

Hi @Samin-roadsurfer, currently, the app is not crashing anymore. I updated to capacitor 6 and also updated all plugins.
