Error when building SvelteKit app with Vite >=6

[bolinocroustibat]

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/sveltekit

SDK Version

9.0.0

Framework Version

SvelteKit 2.17.1 & Vite 6.1.0

Link to Sentry event

No response

Reproduction Example/SDK Setup

@sentry/sveltekit": "^9.0.0" as a dependency
When building with Vite>=6 and Bun==1.2.2, one get the following error:

[vite-plugin-sveltekit-compile] [commonjs--resolver] Failed to resolve entry for package "@sentry/sveltekit". The package may have incorrect main/module/exports specified in its package.json: No known conditions for "." specifier in "@sentry/sveltekit" package
[commonjs--resolver] Failed to resolve entry for package "@sentry/sveltekit". The package may have incorrect main/module/exports specified in its package.json: No known conditions for "." specifier in "@sentry/sveltekit" package

This doesn't happen with Vite<6.0.0, as it was tested with multiple configurations.

Steps to Reproduce

Create a project with:

@sveltejs/kit": "^2.17.1
@sentry/sveltekit": "^9.0.0"
"vite": "^6.0.0"

Use Bun==1.2.2as the bundler.

Expected Result

We would expect a successful build on Vite>=6, as it is the case with the same @sentry/sveltekit.

Actual Result

When building with Vite>=6 one get the following error:

[vite-plugin-sveltekit-compile] [commonjs--resolver] Failed to resolve entry for package "@sentry/sveltekit". The package may have incorrect main/module/exports specified in its package.json: No known conditions for "." specifier in "@sentry/sveltekit" package
[commonjs--resolver] Failed to resolve entry for package "@sentry/sveltekit". The package may have incorrect main/module/exports specified in its package.json: No known conditions for "." specifier in "@sentry/sveltekit" package

This doesn't happen with Vite<6.0.0, as it was tested with multiple configurations.

Hi @bolinocroustibat, thanks for filing this.

I tried this on a fresh sveltekit starter project with bun and the versions you mentioned but didn't run into this.

Could you provide a reproduction repo please?

Hello @andreiborza and thanks for getting back to that so quickly!
Here is a repo with a special branch using @sentry/sveltekit where this has been happening, if that may help:

@bolinocroustibat did you upgrade to @sveltejs/vite-plugin-svelte@5? This version is necessary for vite 6 to work correctly as far as I know. Vite 6 removed a couple of default export condition names that it checks when bundling, and I think this plugin adds them back.
