Many Internal Server Errors - reactjs

Question

Due to some package incompatibilities I have updated my package.json to the latest version for most of the entries, however now when I start the application it displays this long list of errors in the browser:
An error occurred while starting the application.
AggregateException: One or more errors occurred. (Dll Reference Plugin Invalid Options
options.manifest.content['./node_modules/fbjs/lib/invariant.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/fbjs/lib/warning.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/react-dom/lib/reactProdInvariant.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/object-assign/index.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/react-dom/lib/ReactDOMComponentTree.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/fbjs/lib/ExecutionEnvironment.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/jquery/dist/jquery.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/react/react.js']['meta'] is an invalid additional property
And it just goes on and on for about 500 errors. There were no compile errors when the project was built. Here is my package.json:

}
Is anyone familiar with why this is happening? I've searched multiple posts and it seems like people always just have a couple errors. Not 500.

I don't know if you solved it or not , but I had the same problem when I updated to Webpack 4 . The solution was to to run the DllPlugin from webpack.config.vendor.js so that vendor-manifest.json would get the latest attributes.
To do this, in packages.json put this line in the scripts section
"scripts": {
"build": "webpack --config webpack.config.vendor.js",
}
and from console run npm run build
