Error when using with webpack-manifest-plugin

[OlehDutchenko]

I using webpack 5. My config:

/* ... */
plugins: [
    new CleanWebpackPlugin(),
    new MiniCssExtractPlugin({
        filename: '[name].bundle.css'
    }),
    new SVGSpriteMapPlugin('resources/assets/svg/docs/*.svg'),
    new ManifestPlugin({
        basePath: paths.public.base
    })
],
/* ... */

And faced with error

× ｢wdm｣: TypeError: chunk.files.reduce is not a function

What I'm doing wrong or it's ManifestPlugin prodlem. Without ManifestPlugin all works fine...

Which version of webpack-manifest-plugin are you using?

[OlehDutchenko]

next (^3.0.0-rc.0) specialy for webpack 5

Hmm, it definitely looks like an issue with manifest-webpack-plugin, the stack trace you provided points to a TypeError in that plugin where it looks like to be going wrong for a chunk without any files (either created by this plugin or not) which is a valid scenario in Webpack AFAIK.

Please report the issue on that repository. If it ends up needing a fix in this plugin (once a stable release of manifest-webpack-plugin comes out) then feel free to leave another comment and I'll reopen it and will investigate. If that happens, please include a repo that I can use to reproduce the error.
