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?

Self-hosted/on-premise

Which SDK are you using?

@sentry/nextjs

SDK Version

9.31.0

Framework Version

Next.js 15.3.3

Link to Sentry event

No response

Reproduction Example/SDK Setup

See https://github.com/billyjanitsch/sentry-nextjs-ai-bug for a minimal reproduction.

Steps to Reproduce

See repro readme.

Expected Result

In a server actions file, I expect to be able to import and use server exports from ai/rsc:

"use server";

import { createStreamableValue } from "ai/rsc";

assert(typeof createStreamableValue === 'function')

This works fine in vanilla Next.js.

Actual Result

When Sentry's Next.js config is enabled, the above code breaks. ai/rsc resolves to the client implementation instead of the server one, where createStreamableValue is undefined.

This happens from 9.30.0 onwards, presumably because this version enabled automatic instrumentation of the ai library.
