My customer "FindRestaurants" widget and application works well on the ArcGIS Online. When I deployed to IIS server, the Yelp restaurants search didnot show anything. Looks like it didnot search Yelp.
I have followed the deployment steps, and Robert's posts' instructions steps too(Thank you so much Robert). The Yelp API, config.json are setup. The address search works, but no yelp restaurants returned. Anyone has experience about what went wrong?
Here is the production application link.

(I also attached a screen copy of what should the yelp results be. This is the app I created through AGOL. )
