Build broken with Nuxt 3.16.0

[luc122c]

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/nuxt

SDK Version

9.5.0

Framework Version

Nuxt 3.16.0

Link to Sentry event

N/A

Reproduction Example/SDK Setup

https://stackblitz.com/edit/nuxt-sentry-bundler?file=dist%2Fserver%2Fsentry.server.config.mjs

Steps to Reproduce

1. Install Nuxt 3.16.0 & @sentry/nuxt module
2. Install the @sentry/nuxt module (docs)
3. Build the project - npm run build

Expected Result

This is a build on Nuxt 3.15.4:

It does not contain the broken import.

Actual Result

The build output is completely different to Nuxt 3.15.4. It includes an import to a non-existent file:

import { init } from "./node_modules/_sentry/nuxt/build/esm/server/sdk.mjs";

The _sentry folder does not exist.

Importing this module casues the application to crash.

Hi, thanks for reporting and also for opening an issue in the Nuxt repo! I asked @s1gr1d to take a look

What changed in 3.16.0 was that it includes now preserveModules: true when building the server bundle. https://github.com/nuxt/nuxt/pull/31235/files#diff-73d24e0438084e6b6e73889c3113b4fa1c27f2c3e03e70349beed1cadd3c9696R93

Hopefully it saves someone a bit of time when debugging.

Edit: @Ingramz It's probably the change you linked in the comment. I could find the PR: nuxt/nuxt#31235
