Goal
In The New Architecture, when an unhandled exception occurs in a Turbo Module method, React Native throws a JS error with a
causeproperty containing the native exception class, error message and stacktrace.Although the JS SDK supports error causes, these native causes are not parsed correctly in events as they don't contain valid JS stacktraces (the cause stack is reported as
stackElementson Android andstackSymbols/stackReturnAddresseson iOS) - so we end up reporting events with an empty stacktrace in the 'Caused by' error.This PR fixes the error reporting for these cases, so that native 'Caused by' errors are reported correctly with a full native stacktrace while maintaining backwards compatibility with native stack handling for Old Architecture.
(Note: on iOS, exceptions in async Turbo Module methods result in a native crash that is detected by the Cocoa SDK, so this does not apply in those cases)
Changeset
Updated the native stack handling in
delivery-react-nativeto extract thenativeStackproperty for native error causes.Updated
BugsnagEventDeserializer.min the iOS native module to correctly handle events containing multiple errors (the equivalent changes for Android were released in v6.22.0 ofbugsnag-plugin-react-native)Testing
Added new unit test and e2e test cases
