hi all...4th time of trying this skill...now in the service simulator using the utterance 'stop' i get - The remote endpoint could not be called, or the response it returned was invalid.
any help to resolve this issue would be much appreciated.

You've missed something in the README. Look it over again very carefully.

I cannot state this more prominently than this: you have no content in your library. You cannot use Banned addons (wiki) with this skill. The only things you may be able to do are: playback control (play, pause, etc); basic navigation (left, right, enter, etc); and playback queries (time remaining, what's currently playing, etc).

And I do stress the may there. I have not tested anything with zero content in the library.
