If I remove the sentry setup from vite.config.ts, then it works

// import { sentrySvelteKit } from "@sentry/sveltekit";
import { paraglide } from "@inlang/paraglide-sveltekit/vite";
import { sveltekit } from '@sveltejs/kit/vite';
import { defineConfig } from 'vite';

export default defineConfig({
	plugins: [
        // sentrySvelteKit({
        //     sourceMapsUploadOptions: {
        //         org: "prepare-now",
        //         project: "paraglide-sentry"
        //     }
        // }), 
        sveltekit(), 
        paraglide({
            project: "./project.inlang",
            outdir: "./src/lib/paraglide"
        })
    ]
});

HI @jerriclynsjohn thanks for writing in! we'll take a look.

Hey, I have a first update: You can work around this without disabling the entire sentrySvelteKit plugin, by only disabling release injection:

export default defineConfig({
  plugins: [
    sentrySvelteKit({
      sourceMapsUploadOptions: {
        org: "prepare-now",
        project: "paraglide-sentry",
        release: { inject: false }, // <---
      },
    }),
    sveltekit(),
    paraglide({
      project: "./project.inlang",
      outdir: "./src/lib/paraglide",
    }),
  ],
});

If you set a release value in your client and server Sentry.init calls, you loose no functionality.

Also huge thanks for the minimal reproduction! Really appreciate it!

So for once the fix is simple: please update to the latest version of @inlang/paraglide-sveltekit.

This was a bug in paraglide not correctly handling virtual file imports (which our release injection file import is). It was fixed via opral/monorepo#3224 and released with version 0.12.0.

If I upgrade your repro from @inlang/paraglide-sveltekit@^0.11.1 to @inlang/paraglide-sveltekit@^0.15.0, the build passes locally for me. Please let me know if this fixes the issue for you. Thanks!

@Lms24 my bad, I assumed because I scaffolded the project using a CLI, that all packages would be the latest. Thank you so much for the help, mate!

No worries, just glad it works now :)
