When using file-loader and html-loader in webpack the src attr of image is '[object Module]'

Try adding esModule: false option to file-loader like so:

  ...
  {
    test: /\.(jpeg|jpg|png)$/,
    use: [
      loader: 'file-loader',
      options: {
        esModule: false
      }
    ]
  }
  ...

Same applies to url-loader.

esModule option has been introduced in file-loader in version 4.3.0 and in 5.0.0 it has been set to true by default which can be a breaking change.
