Confusing sentry error - user is routed to search from login

Question

I have a social dating Rails 4 website that triggered a Sentry error. In a search controller that returns the closest users within a certain radius:

The exception is NoMethodError undefined method `page' for nil:NilClass and is related to the following line of code:

current_user.longitude).users.page(params[:page]).per(20)

The referrer URL in this request was something.com/login and this request URL was something.com/search. The "page" method comes from the Kaminari gem, a pagination gem. The user logs in and is redirected to a profile page where they can click a "Search" button. My question is: what could possibly be triggering this error and/or why does /search have a referrer URL of /login? There's no search button on the login page. When I test everything manually, everything works as it should.

EDIT: The issue is that the referrer URL is /login on the /search action that is causing the error. However, a person logging in will not be directed to the search action they will be redirected to a profile page where they can then click on the Search button.

Answer 1

the problem is not in the Kaminary, it says "undefined method for nil", which means, the users method for some reason returns nil, that's what you want to check
