Rails 5 - Missing template devise_token_auth/registrations/create

[hoanghiep90]

I used rails g devise_token_auth:install User auth so I have mount_devise_token_auth_for in my config/routes.rb. Like this

namespace :api, defaults: {format: 'json'} do
    scope :v1 do
      mount_devise_token_auth_for "User", at: 'auth'
    end
  end

My gem:

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '~> 5.0.0.beta'
# Fix issues https://github.com/plataformatec/devise/issues/3736
gem 'devise', github: 'plataformatec/devise', branch: 'master'
gem 'omniauth', '>= 1.0.0'

# Token based authentication for Rails JSON APIs
gem 'devise_token_auth', github: 'lynndylanhurley/devise_token_auth', branch: 'master'

When I request: http://192.168.99.100:3000/api/v1/auth ( by POSTMAN )

I get an errors:

Does anyone have any idea?

The problem seems to be caused by jbuilder. Changing the jbuilder gem source to the git master branch gem 'jbuilder', :git => 'git://github.com/rails/jbuilder.git' fixed the problem for me.

@grantsprunger: Wish I had stumbled on this sooner.
Would you mind sharing HOW did you figure this out?
Thank you!

Seems like we have a proposed solution here, so closing for now.
