The issue here is with the view generators.
Do you see, in your path, you are getting users/confirmation.39 for your confirmation route...that 39 is being interpreted as a format by your controller. Its not expecting a user id (#resource) if you have a look at rake routes
the answer here is to remove #resource from your url_helper in the email/view, and if needed, pass ID in as a parameter with the token
user_confirmation_url(confirmation_token: #token, id: #resource)
