Error('no parsers registered for: "' + self.input.slice(0, 5) + '"')

After updating to 2.26.3 Browsersync is throwing an error when used with webpack and webpack-dev-server:

I tried installing previous versions and 2.25.0 works fine. Version 2.26 “works” if I remove the files option, but then of course Browsersync won’t watch for changes at all.

The relevant part of my webpack config file is this:

devServer: {
    hot: true,
    overlay: true,
    stats: 'errors-only'
  },

  plugins: [
    new BrowserSyncPlugin(
      {
        host: process.env.BS_HOST,,
        port: process.env.BS_PORT,
        proxy: process.env.BS_PROXY,
        files: [
          {
            match: [
              '**/*.blade.php'
            ],
            fn (event, file) {
              if (event === 'change') {
                const bs = require('browser-sync').get('bs-webpack-plugin')
                bs.reload()
              }
            }
          }
        ],
        open: false
      },
      {
        reload: false
      }
    ),

    new webpack.HotModuleReplacementPlugin(),

    new webpack.NamedModulesPlugin()
  ]

• Browsersync [2.26.0]
• Node [10.9.0]
• Npm [6.4.1]
• WSL on Windows 10

Yeah its basically because it has too much files to handle or cannot parse some of the files. If I specify only few files it works properly.

I experienced the bug when my Browsersync configuration files array allowed for watching the dir where Composer’s vendor folder was present. Thanks to the comment above I changed files array to exclude vendor folder and left there only folders that I really need BS to watch. No bug anymore.
