How to access devise token auth registration controller?

Question

I am using Devise auth token gem for authenticating some parts of my rails app. But when I try to create a new user with the registration path, it is giving me the following error{"errors":["Authorized users only."]}.

Here is the rspec code that I am using for the test,

it 'creates a user using email/password combo' do
    post api_user_registration_path, { email: 'xxx', password: 'yyy',password_confirmation: 'yyy'}
    puts last_response.body
    expect(last_response.body).not_to have_content('error')
end

Additional info: the model name is 'User' and the routes looks like,

namespace :api do
  scope :v1 do
    mount_devise_token_auth_for 'User', at: 'auth'
  end
end

I understand that the devise is expecting the user to be authenticated before accessing this path, but this being the user registration, it needs to be outside the authentication. Can you suggest a solution for this? Is there any configuration that I am missing here?

Try with:

  namespace :api do
    namespace :v1 do
      mount_devise_token_auth_for 'User', at: '/auth'
    end
  end

This will create the following routes:

        new_api_v1_user_session GET    /api/v1/auth/sign_in(.:format)        devise_token_auth/sessions#new                                                                                                                                  
            api_v1_user_session POST   /api/v1/auth/sign_in(.:format)        devise_token_auth/sessions#create

     api_v1_auth_validate_token GET    /api/v1/auth/validate_token(.:format) devise_token_auth/token_validations#validate_token  

Also create an controller in app/controllers/api/v1/api_base_controller.rb

class Api::V1::BaseApiController < ActionController::Base

  include DeviseTokenAuth::Concerns::SetUserByToken

end

Also add to your file app/controllers/application_controller.rb

  before_action :configure_permitted_parameters, if: :devise_controller?
