Receiving GUID Null Status on create for Payola Stripe Subscription Model

Question

I'm having trouble figuring out why I am receiving {"guid":null,"status":"pending","error":"Email can't be blank"} after I attempt to create a user. Even though, all of the input fields are correct. I cannot get past this point. My server log information is below. Can you help me figure out what the problem is? Lastly, the user is actually saved to the database, but I get a blank screen right after creating one...It doesn't redirect to the target controller. I have a mailing job hooked to the user create model that is meant to fire off an email to the new user. On Stripe, it says I have no active subscribers, even though the user was created. I added the registrations_controller below. I'm trying not to break the code while manipulating the logic.

Plan.rb

class Plan < ApplicationRecord
  include Payola::Plan

  has_many :users
  validates :stripe_id, inclusion: {in: Plan.pluck('DISTINCT stripe_id'),
  message: 'not a valid subscription plan'}

  def redirect_path(subscription)
    '/'
  end
end

User.rb

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  enum role: [:user, :admin, :full_suite, :ultimate]
  after_initialize :set_default_role, :if => :new_record?
  after_initialize :set_default_plan, :if => :new_record?
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
  after_initialize :create_login, :if => :new_record?
  # after_create :sign_up_for_mailing_list
  has_many :clients
  has_many :client_profiles

  belongs_to :plan
  validates_associated :plan
  attr_accessor :login
  has_one :user_profile
  before_create :build_user_profile
  accepts_nested_attributes_for :user_profile
  validate :validate_username
  validates :terms_and_conditions, acceptance: true

  validates :username,
            :presence => true,
            :uniqueness => {
                :case_sensitive => false
            }
  validates_associated :plan

  def set_default_role
    self.role ||= :user
  end

  def set_default_plan
    self.plan ||= Plan.last
  end

  def sign_up_for_mailing_list
    MailingListSignupJob.perform_later(self)
  end

  def validate_username
    if User.where(email: username).exists?
      errors.add(:username, :invalid)
    end
  end

  def subscribe
    mailchimp = Gibbon::Request.new(api_key: Rails.application.secrets.mailchimp_api_key)
    list_id = Rails.application.secrets.mailchimp_list_id
    result = mailchimp.lists(list_id).members.create(
        body: {
            email_address: self.email,
            status: 'subscribed'
        })
    Rails.logger.info("Subscribed #{self.email} to MailChimp") if result
  end

  def create_login
    if self.username.blank?
      email = self.email.split(/@/)
      login_taken = User.where(:username => email[0]).first
      unless login_taken
        self.username = email[0]
      else
        self.username = self.email
      end
    end
  end

  def self.find_first_by_auth_conditions(warden_conditions)
    conditions = warden_conditions.dup
    if login = conditions.delete(:login)
      where(conditions).where(["lower(username) = :value OR lower(email) = :value", {:value => login.downcase}]).first
    else
      if conditions[:username].nil?
        where(conditions).first
      else
        where(username: conditions[:username]).first
      end
    end
  end
end

The response is:

{"guid":null,"status":"pending","error":"Email can't be blank"}

This can happen when params[:stripeEmail] is not submitted in the request.

Payola's CreateSubscription assumes the email is available as params[:stripeEmail] :

module Payola
  class CreateSubscription
    def self.call(params, owner=nil)
      ...

      if params[:stripe_customer_id].present?
        ...
      else
        email = params[:stripeEmail]
      end

      sub = Payola::Subscription.new do |s|
        s.plan = plan
        s.email = email
        ...
      end

      ...

    end
  end
end

Try adding a stripeEmail field to the registration form.
