[IsDyh01]

• Operating System: windows
• Node Version: 12
• NPM Version: 6
• webpack Version:5
• thread-loader Version:4

Expected Behavior

I get this error when I use thread-loader before I use the css loader

Actual Behavior

Code

// webpack.config.js
// If your code blocks are over 20 lines, please paste a link to a gist
// (https://gist.github.com).
config.module.rule('css').oneOf('css-modules').
            use('thread-loader').loader('thread-loader').tap(options => {
                return {
                    ...options,
                    workers: 2,
                };
            }).before('extract-css-loader');

// additional code, HEY YO remove this block if you don't need it

How Do We Reproduce?

I recommend do not use thread-loader and use https://webpack.js.org/configuration/cache/
