Invalid config format

[rpoconn]

I'm seeing this in your karma configuration, webpack is listed by it's self no property.

    config.set({
        webpack,

        // base path that will be used to resolve all patterns (eg. files, exclude)
        basePath: '',

It should probably be webpack : webpack. Either way it's invalid.
