AWS Lambda 无服务器 .Net C# 应用程序错误

Question

尝试使用 Visual Studio 模板在 AWS Lamba 中使用 Lamba 函数时出现错误。当我部署到 lamba 并尝试测试我的功能时，出现以下错误。我并没有真正改变项目的任何内容，只是按原样使用它。

我一直在努力找出问题所在，但无法解决。这真的是我第一次学习 Lamba 和 Serverless Architecture。有什么想法吗？

遇到了同样的问题。在创建项目之前，您需要在 visual studio 中连接到 AWS 资源管理器。在 AWS 控制台门户中创建一个单独的帐户，然后重试。
