NoMethodError at /omniauth/facebook/callback - undefined method `[]' for nil:NilClass

[kspe]

Hi,

I've updated to:

devise_token_auth 0.1.30
ng-token-auth 0.0.24

and now after redirect to /auth/facebook/callback I get:
NoMethodError at /omniauth/facebook/callback undefined method[]' for nil:NilClass`

in

omniauth_success devise_token_auth (0.1.30) app/controllers/devise_token_auth/omniauth_callbacks_controller.rb:24

def omniauth_success
      # find or create user by provider and provider uid
      @resource = resource_class.where({
        uid:      auth_hash['uid'],
        provider: auth_hash['provider']
      }).first_or_initialize

when trying to access auth_hash.

I've tried to clean all browser cache/cookies, removed user from DB in order to have clean installation.

Thanks @ignacykasperowicz - I'll look into this ASAP.

Hey,

As I dived into the code I found out that you've added:
OmniauthCallbacksController#redirect_callbacks before calling omniauth_success or omniauth_failure plus also views has changed.

I'm using in my routes:

if defined?(::OmniAuth)
    get "#{::OmniAuth.config.path_prefix}/:provider/callback", to: 'devise_token_auth/omniauth_callbacks#omniauth_success'
  end

in order to handle the callback before it gets redirected by Angular router with hash # in URL as I use

$locationProvider.html5Mode true

so simply I was redirecting to wrong method in my routes.

I have to dig more into new version of Gem to understand the changes.
I'm closing this issue.

Cheers!

@ignacykasperowicz how did you solve it? I'm stuck with the same problem.

@stefanahman Hmmm, I do not think I was looking at it after in more details, I decided to switch to Ember and used other library for authentication. The issue here was that in devise_token_auth the names of methods had changed I think and that is why I was getting NoMethodError. Sorry I cannot help you more with this.

Hi @kspe , I got the same error using the following request:

GET /api/v1/auth/google_oauth2/callback.json?code=4/hNZXTWia27agrvVUGcbS_LwCIFq00BV0jP6GQ1ViQNM&amz;resource_class=User&redirect_uri= HTTP / 1.1
Host: localhost: 8080
X-Requested-With: XMLHttpRequest
Cache-Control: no-cache
Postman-Token: 9b3760ff-996d-4454-8a77-220f98178ed6

The gem is mounted on the path /api/ v1/auth. Is there a parameter missing in the request?
From what I could find, the auth_hash method returns a null value. Why?
