Can't find postcss config file

[RedHatter]

Example repo

I can't get svelte-preprocess to find a PostCSS config file.

With just

sveltePreprocess()

PostCSS is not processed at all. With

sveltePreprocess({
  postcss: {}
})

PostCSS is ran but I get the erorr message

[svelte-preprocess] PostCSS configuration was not passed. If you expect to load it from a file make sure to install "postcss-load-config" and try again.

Even though postcss-load-config is installed. With

sveltePreprocess({
  postcss: {
    plugins: [ ... ]
  }
}),

everything works as expected but I would like to define an external PostCSS config file.

Hey @RedHatter, set it to true and you should be good to go! See it here in the docs: https://github.com/sveltejs/svelte-preprocess/blob/main/docs/preprocessing.md#postcss-sugarss

Thank you for the quick reply @kaisermann.

I tired you solution but it doesn't seem to work. I still get

PostCSS configuration was not passed. If you expect to load it from a file make sure to install "postcss-load-config" and try again.

See updated repo.

I think you're missing a . dot at the beginning of the filename. postcssrc.json should be .postcssrc.json

edit: even so, seems to not work. will check it

edit2: you're missing the sugarss dependency. The error was omitted, but it's fixed in 4.6.3 🎉
