empty request.env['omniauth.params'] causes exception

[anklos]

Hi there,

I open localhost:300/omniauth/facebook and authorize the app, then I see this error:

NoMethodError in DeviseTokenAuth::OmniauthCallbacksController#redirect_callbacks

undefined method `underscore' for nil:NilClass

in devise_token_auth (0.1.37) app/controllers/devise_token_auth/omniauth_callbacks_controller.rb:14:in `redirect_callbacks'

The line of the code is:

devise_mapping = request.env['omniauth.params']['resource_class'].underscore.gsub("/", "_").to_sym

I set a debugger there and found that request.env['omniauth.params'] is an empty hash {}.

Same issue happened for google oauth login.

Is there any omniauth params I miss in the setup?

Thanks!

I'm getting the same error with facebook oauth. @anklos any luck solving this?

@daudt #540 (comment)

[anklos]

@daudt in summary, use /auth/facebook, not /omniauth/facebook. and pass auth_origin_url in the url query param

[daudt]

@anklos Ok, so I've tried passing auth_origin_url both as a query param and as a header param and I'm still getting the same error. I'm using /auth/facebook:
NoMethodError (undefined methodunderscore' for nil:NilClass)`

I still have this issue on the latest tag v0.1.43.beta1. 0.1.42 was not working either. By this I mean when my redirect was issued to https://my.host/auth/saml/callback?resource_class=User I saw the following error.

I should note this is on a rails api-only app using omniauth-saml

Same error as @caseyprovost here!

same here, actually tried with several strategies, it looks like that request.env['omniauth.params'] is always nil, literally not clear why this is happening also commented about this here

hallo, i still get error when i try access http://localhost:4001/users/auth/google_oauth2?auth_origin_url=localhost:4001/ it still error undefined method underscore for nil:NilClass
anyone can inform me where i have to locate the auth_origin_url ? thanks.

@muhammadyana have you tried to configure the redirect-uri as described here? This solved my issue

[muhammadyana]

@yortz i have tried configure the redeirect_ui, in my devise.rb like
config.omniauth :twitter, ENV['TWITTER_CLIENT_ID'], ENV['TWITTER_CLIENT_SECRET'], redirect_uri: 'http://localhost:4001/users/auth/twitter/callback'
but it still error undefined method underscore for nil:NilClass
here the full code
