I had this error when using ts-loader with HappyPack (this might also apply if you're using thread-loader)

What i did was removed ts-loader from HappyPack but kept it for everything else (e.g. babel)

// webpack config

new HappyPack({
    id: 'babel',
    verbose: false,
    loaders: [
      { loader: 'babel-loader' },
      { loader: 'imports-loader?define=>window.define' }
    ]
}),

... 

module: {
  rules: [
  {
    test: /\.tsx?$/,
    use: ['happypack/loader?id=babel', {
      loader: 'ts-loader',
      options: {
        configFile: require.resolve('../tsconfig.json'),
        allowTsInNodeModules: true,
      }
    }],
  },
}
