适用于Visual Studio Code的AWS Toolkit无法识别有效的SAM模板

Question

我已经安装了针对VSCode的新发布的AWS工具箱，希望通过我的lambda运行调试器（在node.js中实现）。我在插件中创建的lambda取得了成功，即代码镜头出现在app.js中。当我要调试现有的lambda函数时，会出现问题，即使它是有效的SAM模板，也不会出现代码镜头。我还可以通过“ sam --debug-port [...]”命令手动运行调试器，因此我知道问题出在插件上。

这是我的模板：

按照文档中的建议，我还单击了.js文件中的“ aws”标签。

希望有人能成功做到这一点。
