The classes for the input, mutation, and response data not generated

[ERJoseJohnson]

Hi there, hope this repo is still under watch. I've been trying to learn AppSync to build an app with a serverless backend to make API calls. But sadly, I am not able to finish the most pivotal part of the tutorial which is the actual serverless backend with AppSync.

My bet at the moment is that the amplify codegen process might have not run at all, since no classes were generated as per the tutorial. Attached below is a picture of my AWSDataService class that has all the errors. Do let me know if there are further resources you need.
