Found 1 error in node_modules/svelte-preprocess/dist/types/options.d.ts:29

To Reproduce

import preprocess from 'svelte-preprocess'

Expected behavior no error

Information about your project:

• svelte-preprocess version 4.10.7

Additional context workaround is to enable skipLibCheck in tsconfig, which isn't ideal

I at a loss trying to imagine how a critical type error such as this could make it into production.

[DetachHead]

my guess is because this project uses ts-jest which has a critical issue where it skips most type checking

Hey @DetachHead 👋 this will hopefully be fixed in #562.

I at a loss trying to imagine how a critical type error such as this could make it into production.

This is more related to the installed sass version than anything else. At some point, sass changed the signature of the Options type, so here we are.

I've published 5.0.0@next can you try with it?
