I am not seeing Replays for my backend

Issue

I do not see Session Replay recordings for my backend project, even though frontend replays work.

Applies To

  • All SaaS Customers

  • Session Replay

Resolution

Session Replay does not record backend sessions.

Replay recording runs in the browser (or mobile client). Backend errors can still appear on a frontend replay when Sentry can link them with distributed tracing.

What you get instead

  • Backend errors show in Replay Details (Timeline, Breadcrumbs, Errors).

  • Linked backend issues show a Replays tab on Issue Details.

How to verify linking

  1. Keep Session Replay enabled on the frontend.

  2. Enable tracing on both frontend and backend, including trace propagation (for example tracePropagationTargets on the frontend).

  3. From the frontend, trigger an API call that raises a backend error while a replay is recording.

  4. Open that frontend replay and check for the backend error, or open the backend issue and check the Replays tab.

For SDK versions and full setup, use Replays for Backend Errors and the Session Replay docs on backend errors.

If linking still fails, confirm both projects receive events for the same request and that the frontend request URL matches your propagation targets.
