While learning Rails, when I tried to log in from logout, I got an error like the title.

What I did to solve it

First, change the logout action of users_controller.rb as follows.

def logout
  session[:user_id] = nil
  flash[:notice] = "logged out" 
　redirect_to("/login") 
end

Changes

It was fixed by adding flash and changing the redirect destination to/login.
