In this quick lesson we're going to expand our todoHandler.ts lambda function in order to implement a addTodoItem method with AWS.DynamoDB.DocumentClient put operation

When testing the api in insomnia or postman with a put request, my response is 500 error "todo is missing" even though it successfully adds the item to the database.

When I mouse over the 'todo' in the return statement in:

if (httpMethod === "POST") { const todo = await addTodoItem(data); return todo ? createResponse(${todo} added to the database) : createResponse("Todo is missing", 500); }

I'm getting a warning in my editor (VScode) that "an expression of type 'void' cannot be tested for truthiness". I suspect that's the cause however I'm not sure how to fix it. I'll update if I find a solution.

I was missing the last "return todo;" statement in the addTodoItem function. Makes sense it couldn't be evaluated.

todoHandler.handler lambda function cannot be found when invoked It only worked after I compiled with tsc and todoHandler.js is generated.
