Describe the bug

In a project I have, I implement code samples in the docs by doing a raw-loader import of the source code of a component. However, when importing one of these Vue components via the ?raw syntax, running the project fails with a Cannot read property 'line' of undefined error.

This does not happen with, for instance, a raw TypeScript file (commented out in example repo).

Reproduction

Here's a minimum repo, bassed upon a vue-ts template: https://github.com/rymate1234/vite-raw-repro-bug
