We’ve confirmed that our API Gateway and Lambda functions appear to have landed and been configured correctly. Now let’s go perform an operation in the application to verify that these new functions are working. Now, we intentionally didn’t carry forward any data from our monolith database so we’re starting with an empty database. Open the application using the URL you’ve previously saved for your modern application and sign-in with one of the tenants you’re previously created. Now, navigate to the “Orders“ menu item at the top to application and select “Add Order“ from the page that is displayed. Fill out the form that is displayed with some mock order information and save the order by selecting the “Add Order“ button.
You’ll notice that—even though we added an order—no order was actually created. Let’s go take a look at our Order service to see what went wrong.
