Cucumber+Capybara:应用程序外的浏览器重定向的问题

Given I have a rails app
And I'm using cucumber
And I'm using capybara
And I have an action that results in a redirect_to "https://some.other.domain.com/some_path"

Then the in-app portion of the test works fine
But I see this error: No route matches "/some_path" with {:method=>:get} (ActionController::RoutingError)
