devise_token_auth (0.1.31) app/controllers/devise_token_auth/omniauth_callbacks_controller.rb:161:in `generate_url'

      # ensure that hash-bang is present BEFORE querystring for angularjs
      unless url.match(/#/)
        auth_url += '#'
      end

how can i fix this error?

[lynndylanhurley]

What is the value of url?

[danielgatis]

i got nil at omniauth_params['auth_origin_url'] so the url is nil too

[lynndylanhurley]

So the question is, why is omniauth_params['auth_origin_url'] nil? Are you using ng-token-auth or jToker, or are you using a custom client?

[danielgatis]

neither, I'm doing requests from the browser's adress bar

I have the same issue,
If I uncomment it gets added to the db etc.
But no redirect.

And no current_user.

I'm using ng-token-auth

I got same issue here, I using omniauth facebook
I fixed this issue for a moment by modify the omniauth_callback_controller.rb

the @auth_origin_url variable is used by omniauth_response.html.erb for redirecting user, so I though this solution is not perfect

      @auth_origin_url = generate_url(omniauth_params['auth_origin_url'], {
        token:     @token,
        client_id: @client_id,
        uid:       @resource.uid,
        expiry:    @expiry
      })
      # set crazy password for new oauth users. this is only used to prevent
      # access via email sign-in.
      unless @resource.id
        p = SecureRandom.urlsafe_base64(nil, false)
        @resource.password = p
        @resource.password_confirmation = p
      end

      @resource.tokens[@client_id] = {
        token: BCrypt::Password.create(@token),
        expiry: @expiry
      }

      # sync user info with provider, update/generate auth token
      assign_provider_attrs(@resource, auth_hash)

      # assign any additional (whitelisted) attributes
      extra_params = whitelisted_params
      @resource.assign_attributes(extra_params) if extra_params

      # don't send confirmation email!!!
      @resource.skip_confirmation!

      sign_in(:user, @resource, store: false, bypass: false)

      @resource.save!

      # render user info to javascript postMessage communication window
      respond_to do |format|
        format.html { render :layout => "omniauth_response", :template => "devise_token_auth/omniauth_success" }
      end

so I thought it's safe to change generate_url method like this:

BEFORE

    def generate_url(url, params = {})
      auth_url = url

      # ensure that hash-bang is present BEFORE querystring for angularjs
      unless url.match(/#/)
        auth_url += '#'
      end

      # add query AFTER hash-bang
      auth_url += "?#{params.to_query}"

      return auth_url
    end

AFTER

    def generate_url(url, params = {})
      url = '' if url.nil?
      auth_url = url

      # ensure that hash-bang is present BEFORE querystring for angularjs
      unless url.match(/#/)
        auth_url += '#'
      end

      # add query AFTER hash-bang
      auth_url += "?#{params.to_query}"

      return auth_url
    end

I only tested this on facebook provider, I don't know with the others

[booleanbetrayal]

I don't understand the use-case where auth_origin_url or redirect_url would ever be nil ... Can someone please provide a use-case? Right now, this looks like it's stemming from some sort of mis-configuration.
