Describe the bug
We've been attempting to upgrade our project to Svelte 5; so when we upgrade our SMUI packages to use v8, the app throws error pointing to missing '@tsconfig/svelte/tsconfig.json' file

To Reproduce
Steps to reproduce the behavior:

1. Upgrade any component package to v8
2. then attempt to run the app.
3. See error

Expected behavior
Vite should be able to bundle the app and deploy so that it can run.

Svelte 5 requires typescript. The svelte-preprocess should handle it though. Are you using that plugin in Vite?

Yes, I'm using Typescript in our project.
My Vite config has the following bit:

ssr: {
	noExternal: [/^@material\//, /^@smui(?:-extra)?\//]
},

is that what you're asking for?
