The issue seems to stem from https://github.com/styleguidist/react-styleguidist/blob/master/src/scripts/build.ts#L5-L13 on 5.21.2 it returns a Compiler object, on 5.23 it returns null.

_webpack.default(_makeWebpackConfig.default(config, 'production'), (err, stats) => {console.log(stats)})
>> null

webpack.default(_makeWebpackConfig.default(config, 'production'))
>> Compiler {hooks: {…}, webpack: ƒ, name: undefined, parentCompilation: undefined, root: Compiler, …}

It doesn't seem to like the callback

Reproduce
Install Webpack 5.23.0 and run styleguidist build

Version: 11.1.5

Same issue here.

@jasonwilliams did you manage to resolve that issue? :)

[jasonwilliams]

@marcisp sadly not but I hope to look into it soon. Feel free to investigate and add anything you find here it will be useful.

Interestingly i can't reproduce this when building against master, only on 11.1.6
Its because when you yarn link against it it uses webpack 4, eugh

I got same problem, while my webpack version is 5.21.2 and react-styleguidist 11.1.5. Is there any new progress on this issue? SOS！

[jasonwilliams]

I know this may not help your situation, but I moved to storybook in the end. I think it’s unlikely this will get fixed

[github-actions]

🎉 This issue has been resolved in version 11.2.0 🎉

This issue was not resolved for me on react-styleguidist version 11.2.0 . I ended up upgrading from Webpack 5.57.1 to Webpack 5.75.0 which resolved the issue for me. I did not investigate further to see which particular version of Webpack resolves this issue.
