Sentry Anthropic instrumentation breaks `withResponse()`

[jankalfus]

Is there an existing issue for this?

• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

Reproduction Example/SDK Setup

The Anthropic SDK supports calling .withResponse() on the result of client.messages.create(), see https://platform.claude.com/docs/en/api/sdks/typescript#accessing-raw-response-data-e-g-headers. It seems that Sentry's integration does not maintain this API interface, since trying to call withResponse() on a wrapped result ends up with the error: result.withResponse is not a function

I believe this is the same issue as #19073, just for Anthropic instrumentation.

Steps to Reproduce

1. Enable Anthropic integration (on by default)
2. Call client.messages.create({ ... }).withResponse()
3. Error is thrown.

Expected Result

Sentry's integration should not break this API.

Actual Result

result.withResponse is not a function

Hey @jankalfus, thanks for writing in! I'll put this on my list for next week to take a look at.

I was able to reproduce the issue here: getsentry/repro#34

Will try to come up with a fix, should hopefully be straightforward given that we already solved this for the openai integration as you mentioned.
