Twillio Rails not sending

Question

I am trying to add twilio to my rails app using the twilio gem and I am having issues. I first followed this tutorial https://www.twilio.com/docs/tutorials/walkthrough/appointment-reminders/ruby/rails#14 and did it in a separate app which works. However, when I moved it over to my main app its not working. I am not sure if it is because I don't have a specific route for twillio or what. Basically, I have an rsvp button on my site to rsvp to an event and I was hoping when the button is clicked it sends a text. Therefore, I put the code in the RSVP model. I am using delayed_jobs and when the button is clicked it is added to the delayed job queue. However, nothing is actually sent. Is there a way to look at logs for twilio? The code for the rsvp model is bellow. Thanks so much!!

require 'twilio-ruby'
class Rsvp < ApplicationRecord
belongs_to :user
belongs_to :event
validates :user_id, :uniqueness => { :scope => :event_id}

 after_create :reminder
    #
    #
  # @@REMINDER_TIME = 30.minutes # minutes before appointment
    #
  # def when_to_run
  #   time - @@REMINDER_TIME
  # end


  # Notify our appointment attendee X minutes before the appointment time
  def reminder
    @twilio_number = '+18888888888'
    @client = Twilio::REST::Client.new ENV['TWILLIO_ACCOUNT'], ENV['TWILLIO_SECRET']
    time_str = ((self.time).localtime).strftime("%I:%M%p on %b. %d, %Y")
     reminder = "Hi #{self.event_id}. Just a reminder that you have an Event coming up in 30 minutes at #{time_str}."
     message = @client.account.messages.create(
       :from => @twilio_number,
       :to => '+18888888888',
       :body => reminder,
     )
     puts message.to
   end

    handle_asynchronously :reminder, :run_at => Proc.new { 1.minutes.from_now}

end
