Reproduction Example/SDK Setup

import { sentrySvelteKit } from '@sentry/sveltekit';
import { sveltekit } from '@sveltejs/kit/vite';
import { defineConfig } from 'vitest/config';

export default defineConfig({
  plugins: [
    sentrySvelteKit({
      sourceMapsUploadOptions: {
        org: '****',
        project: '****',
        telemetry: false
      }
    }),
    sveltekit()
  ],
  test: {
    include: ['src/**/*.{test,spec}.{js,ts}']
  },
  build: {
    rollupOptions: {
      output: {
        manualChunks: (id) => {
          if (id.includes('layerchart')) return 'layerchart';
          if (id.includes('tiptap')) return '@tiptap/core';
        }
      }
    }
  }
});

Steps to Reproduce

The upgrade to v9 broke our build. We had to revert backt o v8.

Expected Result

It to just build like it did with v8.

Actual Result

failed to load config from backend/vite.config.ts
error during build:

Hi @tcurdt, thank you for writing in.

I tried to reproduce this with a fresh sveltekit starter project with your config (although I noticed sveltekit() is missing in your plugins array) but didn't run into this issue.

Could you please provide a reproduction repo?

Hi @tcurdt, thank you for writing in.

I removed a comment and by mistake also removed the sveltekit() plugin.
Fixed that in the ticket. Sorry about that.

Could you please provide a reproduction repo?

Hm. I'll try.

Could you share the project files of your starter project? Just so we are using off the same project?

@tcurdt sure, here's my repo: https://github.com/andreiborza/15363-sveltekit

I am also running into this issue. I tried cloning your repo @andreiborza and get the same problem:

Node version v22.13.1 if it helps
