SideKiq로 이메일을 보내지 못함 (Job exception: :arguments expected to be an Array of individual string args)

Discourse 2.7.12를 설치하고 Mailgun을 통해 이메일을 보내도록 구성했습니다.

관리 패널을 통해 테스트 이메일은 정상적으로 전송되지만, Sidekiq에서 모든 관련 이메일 작업이 실패합니다.

어떤 오류일 수 있는지 아이디어가 있을까요?

Sidekiq 오류 예시:

Jobs::CriticalUserEmail
{“type”=>“forgot_password”,
“user_id”=>4,
“email_token”=>“ca2fd58bd00511d21d04ca05da6239ad”, “current_site_id”=>“default”
}

관련 코드 (mail/network/delivery_methods/sendmail.rb)

#   Mail.defaults do
  #     delivery_method :sendmail, :location => '/absolute/path/to/your/sendmail'
  #   end
  #
  # Then just deliver the email as normal:
  #
  #   Mail.deliver do
  #     to 'mikel@test.lindsaar.net'
  #     from 'ada@test.lindsaar.net'
  #     subject 'testing sendmail'
  #     body 'testing sendmail'
  #   end
  #
  # Or by calling deliver on a Mail message
  #
  #   mail = Mail.new do
  #     to 'mikel@test.lindsaar.net'
  #     from 'ada@test.lindsaar.net'
  #     subject 'testing sendmail'
  #     body 'testing sendmail'
  #   end
  #
  #   mail.deliver!
  class Sendmail
    DEFAULTS = {
      :location   => '/usr/sbin/sendmail',
      :arguments  => %w[ -i ]
    }

    attr_accessor :settings

    class DeliveryError < StandardError
    end

    def initialize(values)

      self.settings = self.class::DEFAULTS.merge(values)
      raise ArgumentError, ":arguments expected to be an Array of individual string args" if settings[:arguments].is_a?(String)
    end

예외를 발생시키는 것은 initialize 메서드입니다.

Sidekiq에도 SMTP 매개변수를 설정하여 문제를 해결했습니다.

/opt/bitnami/scripts/discourse-env.sh 파일에서

다음 항목들이 export됩니다:

DISCOURSE_SMTP_HOST
DISCOURSE_SMTP_ADDRESS
DISCOURSE_SMTP_PORT_NUMBER
DISCOURSE_SMTP_USER
DISCOURSE_SMTP_USER_NAME
DISCOURSE_SMTP_PASSWORD

하지만 Sidekiq는 DISCOURSE_ 접두사가 없는 매개변수를 기대하고 있었습니다.
따라서 다음 내용을 추가하면 문제가 해결됩니다:

export SMTP_HOST="xxx"
export SMTP_ADDRESS="xx"
export SMTP_PORT_NUMBER="587"
export SMTP_USER="xxx"
export SMTP_USER_NAME="xxx"
export SMTP_PASSWORD="xxx"

테스트 이메일을 보내는 중에 이 오류가 발생합니다. sidekiq에 SMTP 정보를 추가해 보았습니다. 참고: 이 서비스는 k8s에 배포되어 있습니다. 현재 사용 중인 버전은 3.0.6입니다.
