Uncaught (in promise) TypeError: Cannot read property 'keys' of undefined

I'm using the following config:

module.exports = {
  navigateFallback: '/index.html',
  stripPrefix: 'wwwroot',
  root: 'wwwroot/',
  staticFileGlobs: [
    'wwwroot/index.html',
    'wwwroot/**.js',
    'wwwroot/**.css'
  ]
};

root isn't a supported option. Could you remove the root: 'wwwroot/', and see if that helps?
