Datadog Session Replay crash on iOS when recording a date picker

Open marcobeltempo opened this issue 7 months ago • 2 comments

We have consistently encountered a crash caused by the react-native-session-replay library when interacting with a date picker on iOS. Our application hangs and eventually crashes. Based on the stack trace, the ViewTreeRecorder.recordRecursively method seems trapped in a recursive loop.

We have experienced this crash on multiple iOS versions, specifically from iOS 18 to 18.4. We also tried upgrading to dd-sdk-reactnative/releases/tag/2.6.6, but the problem persists.
