Laravel Docker容器出现异常代码错误，请求排查指引

正在学习Docker，尝试将现有Web应用容器化，但连续多日卡在一个毫无逻辑的异常错误上。项目在本地环境、AWS Elastic Beanstalk（通过CodePipeline部署）中运行完全正常，唯独Docker环境里出现这个问题。

错误提示始终指向代码第51行（此前指向第50行）；我在第44行添加了dd调试语句，但dd并未触发，错误依旧指向第51行（添加dd前指向第50行），研究多日仍无法理解原因。

环境细节说明 #

• composer install、npm install及npm run build均执行成功
• public、node_modules和vendor文件夹已加入.dockerignore和.gitignore，这些文件均在容器运行时生成/编译，由PHP-FPM和Nginx提供服务，并未从本地或代码仓库复制到容器中
• 曾尝试将vendor及npm run build后的public文件夹加入代码仓库，问题依旧

希望有人能指明解决方向，这是阻碍我推进其他Web应用容器化的唯一问题。
