Simple solution, don't use the action.. The yelp Json is too complicated for the action. The moment the json has an array, list, etc, it will not work and what you seeing is that the yelp Json has an object (a list).
The actions I built is for very simple json (that you want to save, or send to a server, etc). For anything more complex, then you have to use Datamaker (on ecosystem).
Edit: See intro text if this happens to anybody else.
