Not found. Authentication passthru.

[Hareramrai]

Hi

I am getting "Not found. Authentication passthru." , when clicking on this link http://localhost:3000/users/auth/google_oauth2 .

Below is the server console log details.

Started GET "/users/auth/google_oauth2" for 127.0.0.1 at 2014-09-10 08:54:55 +0530
Processing by Users::OmniauthCallbacksController#passthru as HTML
  Parameters: {"provider"=>"google_oauth2"}
  Rendered text template (0.0ms)
Completed 404 Not Found in 1.7ms (Views: 1.1ms | ActiveRecord: 0.0ms)

Can anyone will guide to solve this issue.

I am using rails 3.2.16 and ruby 2.0

Looks like it must be a setup issue, but I haven't seen that error before. Maybe a bit more information would be useful.

Are you using Devise?
Can you show me what your routes.rb file looks like?
Also how did you define the strategy?
Controller code if available?

I am sure we can easily hunt this down.

@zquestz - I encountered this issue as well. Turns out I was adding omniauth.rb in the initializers. I am using devise and it turns out that I should not add the omniauth.rb initializers as clearly mentioned in the Omniauth Overview docs

@vijayj Does this still pertain to the part in the Omniauth Overview docs where it tells you to use that file to Fix protocol mismatch for redirect uri in Rails? I thought it was only regarding the actual Usage configuration if you use Devise instead of manually setting routes and controllers.

If anyone comes behind, for me the issue was that I was missing the 1.9.1 in my gemfile. Adding that fixed the issue for me. I spent hours checking my code for typos, but it was the gem all along.

gem "omniauth", "~> 1.9.1"
gem "omniauth-google-oauth2"
