/auth/:provider route not registered?

[retorquere]

I'm hitting an issue where omniauth works in dev mode but not in production using passenger. Under passenger, I am redirected correctly by my app to /auth/auth0 (as I use the auth0 provider) but then get an error from nginx that that url doesn't exist. This is my omniauth config:

configure do
  set :sessions, true
  set :session_secret, (ENV['SESSION_SECRET'].to_s == '' ? SecureRandom.base64 : ENV['SESSION_SECRET'])

  OmniAuth.configure do |config|
    # Always use /auth/failure in any environment
    config.failure_raise_out_environments = []
  end

  use OmniAuth::Builder do
    provider :auth0, ENV['AUTH0_CLIENT_ID'], ENV['AUTH0_CLIENT_SECRET'], ENV['AUTH0_DOMAIN']
  end
end

I've ran this to show my routes:

require_relative 'main' # my sinatra app

Sinatra::Application.routes["GET"].each do |route|
  puts route[0]
end

but that shows only these auth-related routes, even in my development environment:

(?-mix:\A\/auth\/([^\/?#]+)\/callback\z)
(?-mix:\A\/auth\/failure\z)
(?-mix:\A\/auth\/logout\z)

but these are all mine, I was expecting /auth/auth0 (or a regex matching it) to be listed too.

It's working for me.
I have these in my config/routes.rb:

  # Auth0
  namespace 'auth' do
    scope ':provider' do
      get 'callback'
      get 'failure'
    end
  end

and when I GET "/auth/auth0" it is rendered as expected (redirecting to the provider):

I, [2017-03-27T17:44:04.437440 #26062]  INFO -- omniauth: (auth0) Request phase initiated.
 => 302 

It may be the destination url of the redirection that isn't configured correctly.

I've converted the app to node in the interim, so I can't replicate the issue anymore, sorry.

I think we can close this issue because nothing in this gem is interfering with Omniauth properly handling 'auth/:provider'

Tested and confirmed, this route is working fine (though it's configured in a few places, which is what might have caused this issue).

Looks like the first route matches?
