问题描述

我创建了一个简单的 Web 应用(无服务器)并使用 Azure App Service VS Code 扩展部署了该 Web 应用.我选择了 Linus + Node LTS 环境.我将部署源配置到本地 Git 存储库(也尝试过远程 GitHub 存储库)并部署.部署显示成功消息.但是，当我浏览该站点时，它会抛出一条消息(3-4 分钟后)，指出存在:( 应用程序错误".管理诊断链接没有显示任何错误.发生这种情况的任何原因?在哪里可以找到错误详细信息?Web 应用程序在本地主机上编译/运行良好.

I created a simple web app (serverless) and deployed the web app using Azure App Service VS Code extension. I chose Linus + Node LTS environment. I configured deployment source to a local Git repo (also tried remote GitHub repo) and deployed. The deployment shows successful message. But when I browse the site, it throws a message (after 3-4 mins) that there was an ":( Application error". The admin diagnostics link doesn't show any error. Any reason why this could be happening? Where can I find error details? The web app compiles/runs fine on the local host.
