Rails 7.1部署后Unicorn报500错误：Array无=~方法

问题概述 #

• 依据Ralf Ebert的《Ruby on Rails – Deployment Tutorial》指南部署Rails 7.1生产环境应用，已完成Nginx配置（对应域名saxshop.sebastiandetering.com），但访问时出现Unicorn 500错误。
• 错误日志显示：undefined method '=~' for [...]:Array (NoMethodError)，触发点为unicorn-6.1.0版本的http_response.rb文件第43行，初步判断是会话头解析异常导致。
• 本地运行应用无任何异常，已将sqlite gem移至development组，此前解决过asset pipeline中javascript.css找不到的问题，确认该问题与此错误无关。
• 已尝试Stack Overflow上相关解决方案，但均未解决问题，现向Unicorn使用者寻求帮助。
