webpack-bundle-analyzer displays a blank page when run from the CLI

Issue description

Hello. When using the plugin the bundle analyzer displays everything correctly. However, I want to use a stats.json file that I’m generating with production flags on.

Unfortunately, the page is just completely blank.

Check your Webpack config file, seems like having stats: 'error-only' is causing the stats.json to have very limited output.

@david-wolgemuth it could be that compression-webpack-plugin is causing your issue, as https://github.com/webpack-contrib/webpack-bundle-analyzer/pull/379 isn’t yet done ☺️
