Can't run all the different endpoints successfully

I was able to:

• list all the todo items
• create a todo item

However, I got 5xx errors when doing at least:

• update a todo item
• delete a todo item
• show a todo item (don't remember if I did or not)

I think the documentation might be old, as the curl commands don't work out-of-the-box after replacing the placeholder id with the actual id. So I used Postman instead, which included the application/json in the header and it worked for listing todos and creating todos.

It seems like the resources are provisioned correctly since todo items are stored and retrieved from dynamodb. However, the other ones wouldn't.

What could be the reason?

首先，使用文档中记录的 curl 命令和 Postman 重现 update、delete 和 show todo 请求，并比较它们的 headers 和路径参数。检查 CRUD 端点的行为以及与 DynamoDB 的交互，以确定 5xx 响应的来源。当原因已记录，并且受影响的端点或 curl 示例能够成功运行时，即视为完成。
