Cannot read properties of undefined (reading 'match') error when using comments without space before text

[Vorion86]

Hi,
after upgrading to version 1.0.0 (and also the latest 1.0.2) I'm getting the following error using the vite plugin (unplugin-preprocessor-directives/vite)

Cannot read properties of undefined (reading 'match')

After some testing, I found that this error seems to occur if a javascript comment does not contain a space after "//".
This comment creates an error : "//error comment", while this works without any issue "// working comment".
I've also created a playground demonstrating the issue at stackblitz:
https://stackblitz.com/edit/vitejs-vite-hy77nf?file=package.json,src%2FApp.vue
(Comment is in App.vue)

Thanks.

Edit: After rechecking stackblitz with Firefox I get an erorr saying "comment is undefined", Chrome shows the error above.
