Hello! I tried to use this plugin with webpack 5 and webpacker 6 and if I use it I have this error. Commenting plugin and everything works. Do you have any ideas how can I try to debug this issue?

Hello, I know this is closed, but I wanted to comment here incase someone else comes across this.

I've experienced this issue on webpack 5, using RedwoodJS (which uses this under the hood). The problem was that my public folder already had a manifest.json - so when this plugin tries to produce another manifest, it caused the build to fail.

I configured the output path like this 

        new WebpackManifestPlugin({
          fileName: 'rw-build-manifest.json', // different filename
        }),

and now the error is gone :)
