Ruby - Can't review a new page

Hi,

I’m beginner with Prismic, I added a new page, and I added these dependencies at the codebase in: link_resolver, pages_controller.rb, application.rb, routes.rb, sitemap.rb and routes,yml,

my problem is can’t preview this new page, knowing that the preview works for the old pages, I use Ruby, for the preview its added lik this:

I don’t know way it doesn’t work, is I have to publish the page or push my code, can you help me?

Thank you in advance!

Hi,

for more information when I click on review it show me 404 error,
I have another problem, this time I edited an existing page but when I click on review nothing was changed!

We discussed the in a private messaged and it seems it was a problem with the ubuntu package.
