ruby-on-rails - Sidekiq Twilio Redis 'undefined method ` strip' for nil :NilClass'

Question

我正在使用 sidekiq 和 twilio 在指定时间发送文本。

我的 message_worker.rb 包含以下内容:

class MessageWorker
  include Sidekiq::Worker

  sidekiq_options retry: false

  sidekiq_retries_exhausted do |msg|
    Sidekiq.logger.warn "Failed #{msg['class']} with #{msg['args']}: #{msg['error_message']}."
  end

  def perform(id)
    record = Textmessage.find id
    @twilio = Twilio::REST::Client.new ENV['ACCOUNT_SID'], ENV['AUTH_TOKEN']

    @twilio.account.messages.create(
      from: ENV['ACCOUNT_PHONE_NUMBER'],
      to: record.phone_number,
      body: 'This is your scheduled reminder to view a house.'
    )
  end
end

我的 redis.rb 包含以下内容:

uri = URI.parse(ENV["REDISTOGO_URL"])
REDIS = Redis.new(:host => uri.host, :port => uri.port, :password => uri.password)

我收到以下错误消息(为了便于阅读，我将其隔开):

我需要在 ENV 文件中设置我的凭据。格式如下:

heroku config:set GITHUB_USERNAME=joesmith
