ERROR in The "path" argument must be of type string. Received an instance of Object

[blasterbug]

When compiling after updating from copy-webpack-plugin@6.0.0 to 6.0.1, I got this error (that seems be thrown by mini-css-extract-plugin).
"""
TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received an instance of Object
"""

I am not sure if it's an actual bug, but I post this here since the only thing that changed when I got this error is the version for mini-css-extract-plugin.

I can try to make a minimal project to reproduce the errors, but seems overkill for me right now.

• Operating System: MacOS 10.15.4 (happen also int he Google Cloud build environment)
• Node Version: 14.2.0 (and node:13-alpine on Gcloud build)
• NPM Version: 6.14.5
• webpack Version: 4.43.0
• copy-webpack-plugin Version: 6.0.1

Minimum - please provide full stack trace of an error

@blasterbug You should update how you call copy-webpack-plugin. I managed to make it work by doing the following:

module.exports = () => ({
  //...
  plugins: [
    new CopyWebpackPlugin({
      patterns: [
        {
          from: 'public',
          globOptions: {
            ignore: ['public/service-worker.js'],
          },
        },
      ],
    }),
  ],
)}

Also mini-css-extract-plugin and copy-webpack-plugin uses difference hooks, please update the issue using template and I will reopen the issue, can't help without configurations/reproducible test repo/reproducible steps

[blasterbug]

this is how I set up the copy plugin:

new CopyWebpackPlugin({
        patterns: [
          {
            from: path.resolve(__dirname, 'public'),
            to: path.resolve(__dirname, 'dist'),
            globOptions: {
              dot: true,
              gitignore: true,
              ignore: [
                '*.html',
                '*.svg',
              ],
            },
          },
        ],
      }),

And this what I've got:

Child mini-css-extract-plugin node_modules/css-loader/dist/cjs.js??ref--4-1!node_modules/postcss-loader/src/index.js??postcss!node_modules/sass-loader/dist/cjs.js!src/styles/main.scss:

Looks like bug in globby
