To test the failure:

1. npm install
2. start mongo in a terminal
3. run node index.js
4. send a REST CURL

curl -X POST -H 'X-Parse-Application-ID: hello' -H 'X-Parse-Client-Key: world' http://localhost:1337/functions/hello

-> notice the result {"code":141,"error":{"message":"unauthorized"}}

Working version: run JAVASCRIPT_KEY=h node index.js

run the curl notice the result {"result":[]} the query is run and returns nothing
