not getting any business object in MAX- data mapper

Content

Hi,

I have created custom API.

and these are my end point::

security login required NO::

after that I wrote code in Node JS: I am attaching that file here::

Haven't written schema and mock code inside endpoints.

Now, In max application, I want to use the 1st and 3rd endpoints in above snapshot.

So, In max, I want a list of all cities and when I select any city I want stores list for selected city.

Please check attached javascript file and JSON object written in that so you can understand what I am talking about.
