我想在Heroku上部署我的Sping Boot 应用程序。当我尝试手动部署时，日志上没有错误。但当我尝试加载网站时，出现以下错误：

Application error
An error occurred in the application and your page could not be served. If you are the application 
owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail

请在下面找到我的日志。有人有什么想法吗？我错过了什么吗？任何帮助都是欢迎的！
