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

Without reproducible test repo I can't help, sorry

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'],
          },
        },
      ],
    }),
  ],
)}

[alexander-akait]

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

sindresorhus/globby#145

gitig

With copy-webpack-plugin 6.0.3, I'm also getting "ERROR in The "path" argument must be of type string. Received an instance of Object". The error is just that, no additional information and there is no clear indication that the failure is coming from copy-webpack-plugin (but it definitely is).

The error goes away if I do not use gitignore: true

My configuration:

		new CopyPlugin({
			patterns: [
				{
					from: './',
					to: '../dist/',
					context: './src/',
					globOptions: {
						dot: true,
						// gitignore: true, //In "copy-webpack-plugin": "^6.0.3", causes: ERROR in The "path" argument must be of type string. Received an instance of Object
						ignore: ['**/*.ts', '**/*.tif*', '**/*.tif', '**/*.md', '**/*.js', '**/libs/**', '**/*.doc'],
					},
				},
			],
		}),
	],```

@gregbenz Feel free to send a fix to globby

@gregbenz Feel free to send a fix to globby

@evilebottnawi Sorry, I'm not sure what you mean. What would I do to use the gitignore flag without errors?

[alexander-akait]

Send a fix to globby, here issue sindresorhus/globby#145

[alexander-akait]

It is not problem by typescript, it is problem in globby package

[gregbenz]

Thank you for catching that, I had multiple tabs opened and copied to the wrong one. Deleted from TS and added to globby.
