Tanstack Start's server integration doesn't send to sentry

[nick-potts]

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Sentry Saas (sentry.io)

Which SDK are you using?

@sentry/tanstackstart-react

SDK Version

9.38.0

Framework Version

1.127.3

Link to Sentry event

No response

Reproduction Example/SDK Setup

https://github.com/nick-potts/sentry-tanstack-start-basic

I've taken the basic-start from the tanstack docs and followed the instructions for adding it. The only things I've done differently:

• Client Sentry is enabled: false. The client stuff works, so I disabled it in this repo.

Steps to Reproduce

Browse to boom and api-boom. neither fire server side events.

Note, the beforeSend is triggering, just nothing gets sent to sentry.

Expected Result

Events are sent to sentry

Actual Result

No events are sent from the server client

Hi @nick-potts, thanks for filing this and providing a reproduction repo. We'll take a look.

I just took a look at your reproduction and you are definitely right to question this. The SDK is currently in Alpha state and mainly offers functionality for the client-side. Automatic error monitoring on the server-side is not yet included. I updated the docs and the tracking issue to make the current state more obvious.

• Tracking Issue: [JavaScript] TanStack Start SDK #14990
• Docs: docs(tanstackstart): Add alpha notice sentry-docs#14380

I will close this as this is not a bug, but a feature that was not yet implemented. You can always capture errors manually with captureException. However, automatic error capturing requires the Nitro server to be instrumented.

Thanks for the info, just to be clear - nothing works server side yet? No spans, errors, logs etc?

If you call the functions manually it works, but automatic instrumentation (without you having to call the functions) for TanStack Start's current server setup is not yet implemented.

As TanStack Start is still on v0 and they plan to use Nitro on the server with v1, we want to optimize for their Nitro setup in v1.

Are you not seeing logs because you are running tanstack start on a serverless environment, like Cloudflare Workers? That would shut off the compute before sentry could flush
