CHANGELOG.md


+- Add handling for HTTP 413 (Content Too Large) responses from Relay ([#5566](https://github.com/getsentry/sentry-react-native/issues/5566))
+  - SDK now logs actionable error messages when envelopes are rejected due to size limits
+  - Prepared infrastructure to capture HTTP status codes from native transport layer for future enhancements


nit: I think we could skip this from the changelog since it is not a user facing change

Suggested change

- Prepared infrastructure to capture HTTP status codes from native transport layer for future enhancements

+    // TODO(alwx): Capture transport response from sentry-cocoa when available


The iOS implementation may arrive soon in a next Cocoa 9.x.

could add it once it's there, shouldn't be too urgent anyway

We released this yesterday with 9.3.0. But the transport doesn't expose the response code. It simply logs an error. Don't these Cocoa SDK logs don't show up in your RN logs? If yes, then all good nothing to do. If not, we need to align on how we can communicate this. This won't be straight forward, because we first store envelopes to disk and then send these async.

Removed that changelog entry in the last commit

antonis

I was thinking that we may not need to ship any code for #5566 (similar to #5390) and just rely on the native SDK implementation (iOS, Android).
We can mark the issue as done once we ship an RN version with that includes both the native implementations. Wdyt @alwx @lucas-zimerman @philipphofmann?

lucas-zimerman · 2026-01-29T15:36:41Z

packages/core/src/js/wrapper.ts

+    const response = await RNSentry.captureEnvelope(base64StringFromByteArray(envelopeBytes), { hardCrashed });
+
+    if (response?.status) {
+      const statusCode = parseInt(response.status, 10);


Thank you for the PR!, the solution is nice, but I fear just parsing an integer from a string may be flaky when other types of error happen. Would it be possible to return the statusCode as integer and the errormessage on separated parameters on the native side?
