title: Plugins[0][1] must be an object, false, or undefined
body: <p>I have been trying to upgrade my packages and things have started to fall apart and I am now unable to build and cannot seem to figure out what is the issue. I suspect the issue is related to the <code>.babelrc</code> file as it is a babel-loader error being thrown.</p>
