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，使用文件中記載的 curl 指令和 Postman 重現 update、delete 和 show todo 請求，並比較它們的 headers 和路徑參數。檢查 CRUD 端點的行為以及與 DynamoDB 的互動，以找出 5xx 回應的來源。當原因已記錄，且受影響的端點或 curl 範例能夠成功運作時，即表示完成。
