Draft links in runway

iu tried to add page news/[newsslug:s]/preview to the routes but then get a blank page

There are no errors, I am getting the standard runway page not found. If I take the news item out of draft it works fine.

as in news/[newsslug:s]/[preview:preview] That gives the news post page without the article.
