Automatic sveltekit load instrumentation causes vite bundle errors with duplicate identifier "load"

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

7.64.0

Framework Version

1.22.6

Link to Sentry event

No response

SDK Setup

Sentry.init({
    dsn: "https://7f6570917828021f8dea53dc2b778775@o1098001.ingest.sentry.io/4505744165699584",
    tracesSampleRate: 1
})

Steps to Reproduce

I added the Sentry SDK to a Sveltekit project using the wizard.

My vite config is:

export default defineConfig({
  plugins: [
    sentrySvelteKit({
      sourceMapsUploadOptions: {
        org: "million-marker",
        project: "future",
      },
      debug: true,
    }),
    houdini(),
    sveltekit(),
    Icons({ compiler: "svelte" }),
    svg({
      svgoOptions: {
        plugins: [
          {
            name: "preset-default",
            params: { overrides: { removeViewBox: false } },
          },
          {
            name: "prefixIds",
          },
        ],
      },
    }),
  ],
  ssr: {
    // Prevent crashes in SSR when Felte forms are used. See
    // https://github.com/pablo-abc/felte/issues/201#issuecomment-1381641343
    noExternal: ["felte"],
  },
});

Expected Result

No crash when running in development

Actual Result

Upon starting a dev server, I immediately receive errors due to the automatic load instrumentation. With the plugin debug option enabled:

@fnimick

Hi @fnimick thanks for reporting this! Hmm looking at your config, it seems like you have quite a few plugins running that might interfere with our auto instrumentation in some way. I have a hunch that it might be houdini, given that a very similar issue was reported a couple of days ago (#8846). Can you try removing houdini and check if this solves the issue?

As I wrote in #8646, we'll look into Sentry+Houdini next week.

If it turns out not to be related to Houdini, please try to narrow it down to a specific plugin combination and if possible, provide a minimal reproduction example that we can use to reproduce this. Thanks!

@Lms24

@Lms24 ah, you were right, it is a Houdini compatibility issue. I didn't expect it since houdini was not in use at all on the route that was causing the error.

@fnimick

@fnimick I opened #8881 which should fix this issue. It'll go in the next patch or minor release after today's release.

fix(sveltekit): Ensure target file exists before applying auto instru…

@Lms24

@Lms24 I am getting the same error using

"@sentry/sveltekit": "^9",
"houdini": "^1.5.1",
"houdini-svelte": "^2.1.5"

@ahsanswr

~~This will be fixed with 9.2.0 releasing on Monday :)~~

sorry, I mixed up issues, let me take another look

update: @ahsanswr can you provide a minimal reproduction? Do you get exactly the same error as reported? We previously considered this fixed. If it's not the same error, please open a new issue and fill out all details. Thanks!

Yes it seems to be exactly the same error:

I will create a reproduction but in short, it occurred after running the following commands in a sveltekit 2 project.
npx houdini@latest init
npx @sentry/wizard@latest -i sveltekit --saas --org orgname --project projname
