Crash with EXC_BAD_ACCESS on _jsMessageThread->runonQueue(onComplete) After Multiple Logins/Logouts #384

Closed dheeraj-bartwal closed 1 day ago

dheeraj-bartwal commented 2 months ago

We are experiencing a crash with the exception EXC_BAD_ACCESS when calling _jsMessageThread->runonQueue(onComplete) after multiple login and logout cycles. The crash log indicates an attempt to dereference a null pointer, which appears to be linked to the object lifecycle issues with _jsMessageThread. Steps to Reproduce:

Perform a login. Log out. Repeat the login/logout process several times. Observe the crash occurring intermittently. Expected Behavior: The application should handle multiple login and logout cycles without crashing. Specifically, the _jsMessageThread object should be managed correctly across these cycles.

Actual Behavior: The application crashes with an EXC_BAD_ACCESS error due to attempting to dereference a null pointer when accessing _jsMessageThread.

Crash Log: Exception - This event error 10:29:24.000 EXC_BAD_ACCESS: release > Attempted to dereference null pointer.

Additional Information: "SalesforceMobileSDK-iOS version": "12.0.1", "react-native": "0.70.14", "react-native-force": "git+https://github.com/forcedotcom/SalesforceMobileSDK-ReactNative.git#v11.1.0",

You are mixing up versions: Mobile SDK 12.0.1 should use SalesforceMobileSDK-ReactNative#v12.0.1 which uses RN 0.73.6. Did you run forcereact to generate your application?

dheeraj-bartwal commented 2 months ago

@wmathurin Yes, I used forcereact to create the application. How can I downgrade SalesforceMobileSDK-iOS to version 11.1.0? When I create a new app using forcereact create, it defaults to SalesforceMobileSDK-iOS v12.1.0.

First uninstall forcereact (see doc). Then install the 11.1.0 version by doing npm install forcereact@11.1.0. Do npm install -g to install it globally.

Closing issue - please check last comment. Re-open issue if it still happens (and you are using the most recent Mobile SDK 12.2).
