Hello,

I am going through the tutorial and am getting this error:  
TypeError: lambda is not a function

I am on the Chapter: “Building a Serverless API” and have added the create.js file as described.

I am at the point where I am running this command: serverless invoke local --function create --path mocks/create-event.json

I am not sure what is causing the issue after my investigations.

Github containing this project:

> **[nickmchou/Athena-Test](https://github.com/nickmchou/Athena-Test)**
>
> Contribute to nickmchou/Athena-Test development by creating an account on GitHub.

Any help would be really appreciated. Thanks

Not sure what the exact issue is but the `uuid` package doesn’t seem to be in your `package.json`?
