Cannot read property 'contents' of undefined during build

See original GitHub issue

Using webpack v 4.29.6, my build fails at fontmin-webpack/lib/index.js:129, I get this error :

byExtension[item.extension].contents

TypeError: Cannot read property 'contents' of undefined

Here is some of my webpack config file : (I am also loading some .gif and .png files with file-loader, maybe it’s causing a conflict?)

module.exports = {
    mode: 'production',
    entry: entryObject,
    module: {
        rules: [
            {
                test: /(\.scss)$/,
                use: [
                    {
                        loader: MiniCssExtractPlugin.loader
                    },
                    {
                        loader: "css-loader" 
                    },
                    {
                        loader: "sass-loader",
                        options: {
                            implementation: require("node-sass")
                        }
                    }, 
                    {
                        loader: "postcss-loader",
                    }
                ]
            },
            {
                test: /\.(woff(2)?|ttf|eot|svg|gif|png)(\?v=\d+\.\d+\.\d+)?$/,
                use: [{
                        loader: 'file-loader',
                        options: {
                            name: '[name].[ext]',
                            outputPath: '../fonts/'
                        }
                    }]
            },
        ]
    },
    plugins:
            [
                new MiniCssExtractPlugin({
                    filename: "../css/[name].css",
                    chunkFilename: "[id].css",
                }),
                new OptimizeCSSAssetsPlugin({}),
                new FontminPlugin({
                    autodetect: true, // automatically pull unicode characters from CSS
                }),
            ],
    devtool: false,
    }

Have you given it a shot with v2.0.4? I published what should be a fix for this error message but didn’t have a bug repro so 🤷‍♂
