Missing source file with a matching Debug ID on SvelteKit & Cloudflare

[tarekfb]

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

9.5.0

Framework Version

2.5.10

Link to Sentry event

https://digitutor-dev.sentry.io/issues/32624244/events/52d2d2175dbc48d58466599eedaf6041/

Reproduction Example/SDK Setup

Things I've tried:

• set values for args sentrySvelteKit() in config obj

 sentrySvelteKit(
      {
        adapter: 'cloudflare',
        sourceMapsUploadOptions: {
          org: 'my-org',
          project: 'my-proj',
          authToken: env.my-token,
        }
      }
    )

• ran in dev mode

I read in an older github issue that source maps arent optimised for non-production builds. How can I ensure it is a non-production build?
I did run build & preview for both environment: 'local' and environment: 'prod', in the init function for sveltekit hooks.

Docs also says "@sentry/sveltekit will generate and upload source maps automatically", however i followed wizard anyhow. Everything else is working fine, sentry wise.

In the modal/guide on sentry I'm at step "Missing source file with a matching Debug ID", with following info

No Source File With Matching Debug ID
You already uploaded artifacts with Debug IDs but none of the uploaded source files had a Debug ID matching this stack frame's Debug ID: 7056a63a-784e-4423-9f7f-599705af8b59

Make sure to inject Debug IDs into all of your source files and to upload all of them to Sentry.

Steps to Reproduce

1. Generate an error, in in client or server
2. Look for source maps at sentry event in saas

Expected Result

Have full stack trace with source maps

Actual Result

Stack trace without source maps.

Source maps just worked on a remote environment hosted on cloudflare for a client side error. Previous testing was on localhost, on both dev mode and production builds (vite build & vite preview scripts)

Hey, thanks for writing in!

I read in an older github issue that source maps arent optimised for non-production builds

I don't understand what this means. Source maps are enabled by the sentrySveltekit() plugin if you're building for production and you didn't enabled or disable source maps yourself.

To debug this, I need to know more about how you build your app. Please provide the exact build command that you use to build the artifacts you deploy. Also any further information on how you build your application would be appreciated. Thanks!

Stack trace with source maps works on client side, but does not work on server side.

Build commands on cloudflare build configuration:

Build command: npm run build
Build output: .svelte-kit/cloudflare
Root directory: 
Build comments: Enabled

and the build script corresponds to:
"build": "vite build",

Do you need any other information?

Build commands on cloudflare build configuration

Does this mean you build on Cloudflare directly somehow? The build flow I tested so far was to run

1. npm run build
2. wrangler deploy (which deploys the previously generated artifacts).

(be that directly locally or in CI)

Other means of building and deploying might produce unexpected outcomes like this one. We can investigate these further but we might run into limitations we can't solve.
