Deployment on Netlify using SvelteKit succeeding during build but failing during requests (Cannot find module '@sentry/bundler-plugin-core/sentry-release-injection-file')

[kyllerss]

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

7.80.0

Framework Version

1.25.2

Link to Sentry event

No response

SDK Setup

Sentry.init({
    dsn: <...>,
    tracesSampleRate: 1
});

Steps to Reproduce

Deploy a build in Netlify and access any of the site's URLs. I enabled Sentry integration through Netlify's UI. I also enabled GitHub integration.

I used the SvelteKit wizard CLI tool to enable code changes in the app. Local testing and building work fine.

Expected Result

Should be able to see the homepage without any issues.

Actual Result

The build and deploy process complete successfully, however when I access the site's homepage I get a 500 error. The serverside console shows the following error:

I may have stumbled upon what I assume is the cause: according to Sentry's SDK GitHub documentation, SvelteKit adapter-netlify is not listed as a supported target. This could be an example of an unfortunate coverage gap in feature support: Netlify is touting its Sentry support, while also explicitly supporting many frameworks (SvelteKit being one of them). I don't see anything in their documentation stating their support is partial.

Is this outdated documentation or am I out of luck?

[lforst]

I don't think adapter-netlify is supported as of now. I also don't think this is a priority for us at the moment so I wouldn't expect this to land too soon. PRs are always welcome!

I'll have @Lms24 confirm all of this though as he is our go-to person for all things SvelteKit.

[Lms24]

Hi @kyllerss, @lforst is correct. Unfortunately, we don't have time to work on SvelteKit adapters at the moment.

[kyllerss]

Thanks for the clarification (perhaps a documentation update in the meantime?)

[Lms24]

Our documentation already states that we don't support the netlify adapter out of the box. As for Netlify's documentation, they might want to update it in the meantime but I'd recommend opening an issue on their end. Thank you!
