has anyone tried Meraki Adventure API Lab 1.0?

[EdgeFarming]

Hello, 

I'm very new in Meraki API's and I wanted to start with a first easy lab from Meraki:

https://docs.google.com/document/d/1EKLD9rRV82D6ablebvhll0LtV2VJMC4mHRxUjv-Qots/edit

But it doesn't work! 😞

It involves AWS Lambda and API Gateway.

If someone has done it and it worked, give me a hand.

Thanks
