Sidekiq delayed mailer cannot find module

Question

I have followed instructions on sidekiq delayed extensions as per: https://github.com/mperham/sidekiq/wiki/Delayed-Extensions

Using sidekiq version 2.14.1

class ContactController < ApplicationController
  def create
    contact = params[:contact]
    ContactMailer.delay.email_support(contact[:name], contact[:email], contact[:phone], contact[:category], contact[:details])
    redirect_to contact_path, notice: t("contact.email_support.sent_confirmation_flash")
  end
end

#/app/mailers/contact_mailer.rb
class ContactMailer < ActionMailer::Base
  default from: "[email protected]"

  def email_support(name, email, phone, category, details)
    @name = name
    @email = email
    @phone = phone
    @category = category
    @details = details
    @title = "#{t('contact.email_support.title')} - #{@category}"
    mail(:to => "[email protected]", subject: @title)
  end
end

For some reason I'm getting an undefined class/module error:

My sidekiq queue looks like this:
