Jipster Client Only App Error Non-abstract class 'AuthExpiredInterceptor' - jhipster

Question

Hi I'm trying to install a client only version of jhipster.
I have used the following commands:
yo jhipster:client through yarn
but no luck, same with:
yo jhipster:client --npm --auth
and I still get the same error.
The server side generates fine but the client side is causing problems.
I'm on node: v7.7.1

Start your Webpack development server with:

found it:
yo jhipster:client --auth jwt
the --help flags are not well documented for auth types but works though
