@use should grab _index.scss when pulling in an npm package that has a js file for main

This is related to #804 and #535

• Operating System: MacOS/Docker
• Node Version: 13.3.0
• NPM Version: 6.14.4
• webpack Version: 4.29.6
• sass-loader Version: 9.0.2
• sass Version: 1.26.10
• fibers Version: 5.0.0

I'm using sass and fibers rather than node-sass

Expected Behavior / Situation

I'm using an NPM module with both js and scss pieces. The main attribute in package.json is dist/main.js, the sass attribute is _index.scss. I would like to be able to import my js with import module from 'module'; and import my scss with @use '~module';

Actual Behavior / Situation

The sass fails to build unless I change the import statement to @use '~module/index';. I can also get this to work by changing the main attribute in the modules package.json to point to _index.scss.

Modification Proposal

A comment in #535 suggests I may be able to use webpack's resolve as a workaround, but as per the Sass docs, calling @use on a directory should automatically pull in the _index.scss file.

I had a typo. Things work as expected. Sorry for the spam.
