Stylus Composes Fails with CssSyntaxError

[willdawsonme]

We're using css-modules-require-hook server-side with stylus as our preprocessor, but with versions 4.2.2+, we get this error when trying to execute the hook. Any ideas? Would like to use 4.2.3 for the resolve alias configuration.

CssSyntaxError: postcss-modules-resolve-imports: /Users/william.dawson/Documents/network/honey-2018-website/node_modules/@nec-network/latest-feed/lib/components/LatestFeed/latest-feed.styl:4:1: Missed semicolon

This happens when composing a stylus file from another stylus file:

.latestFeed
    composes: latestFeed from "../../../../node_modules/@nec-network/latest-feed/lib/components/LatestFeed/latest-feed.styl"

It seems like the preprocessor runs on the original file, but then when postcss-modules-resolve-imports runs, it runs postcss on the stylus file, not the preprocessed file.
