Rails doesn't recognise my app/services (uninitialized constant)

Question

I am stuck and even if I found some subjects about this issue, I didn't found any solution.

I am trying to add a subscription to Mailchimp if my "Packer" register to our newsletter (A "Packer" is a kind of "User" - "User" only has the Devise parameters and "Packer" has the rest)

The error is an uninitialized constant, It seems to be because rails doesn't recognize my service.

Here is my #app/models/packer.rb

after_create :subscribe_to_newsletter
after_update :subscribe_to_newsletter
private
def subscribe_to_newsletter
  SubscribeToNewsletterService.new.call(self.user) if self.newsletter
end

and my # app/services/subscribe_to_newsletter_service.rb

require "gibbon"
class SubscribeToNewsletterService
  def initialize
    @gibbon = Gibbon::Request.new(api_key: ENV['MAILCHIMP_API_KEY'])
    @list_id = ENV['MAILCHIMP_NEWSLETTER_LIST_ID']
  end
  def call(user)
    @gibbon.lists(@list_id).members.create(
      body: {
        email_address: user.email,
        status: "subscribed",
        double_optin: false,
        # merge_fields: {
        #   FNAME: @user.first_name,
        #   LNAME: @user.last_name
        # }
      }
    )
  end
end

Looking into the different solutions, I also added that line in #config/application.rb

module Pyswebsitev1
  class Application < Rails::Application
    @config.autoload_paths += %W(#{config.root}/app/services)
    config.i18n.default_locale = :en
  end
end

When I do a rails console - ActiveSupport::Dependencies.autoload_paths The result include /app/services

I also tried to "Spring stop", to reboot server, and to bundle.

If you have any idea, that would be very helpfull ! Thank you very much

Maybe you forgot to put the _service in your filename event if you put it in your question. Just guessing ...
