ERROR in directoryPaths.map is not a function

webpack 5.89.0 compiled with 1 error in 5365 ms

ERROR in directoryPaths.map is not a function is thrown with no additional stacktrace or context. This was not happening in latest 11.x versions.

Configuration:

    new CopyPlugin({
      patterns: [
        {
          from: '**/*',
          context: path.resolve(__dirname, 'public'),
          globOptions: { ignore: '**/index.ejs' }
        }
      ]
    }),

Expected Behavior

The webpack build should pass successfully instead of terminate mid-processing and copy in assets from public directory

The bug (regression) in globby https://github.com/sindresorhus/globby/issues/262, we can't fix it here, currently you can fix it change ignore: '**/index.ejs' to ignore: ['**/index.ejs'], i.e. as an array

[pachuka]

Ahh, I missed that, much appreciated for the quick response/workaround.

[alexander-akait]

I think we can't fix this because of https://github.com/mrmlnc/fast-glob/releases/tag/3.3.1, it looks like string is not supported since 2018 and this worked just fine thanks to luck, just change it to an array

[pachuka]

Yep, agreed was following that chain. Updating to the array did solve the issue. Given 12.x is a major release this "breaking" is OK and hopefully folks will see this issue if they run into it :). Appreciate the help!

Not sure if you can edit the release notes on the 12.0.0, but if so, maybe worth noting that there.

@pachuka Feel free to send a PR with this updating, I am fine with it
