What should be the callback url in OpenFB.init('app_id','https://localhost:8100/openfb/index.html');

ionic-v1
1

I am following this OpenFB tutorial. for that

  1. I created a new project
  2. then added the www folder from OpenFB to my project LeaveManager
  3. created new facebook app
  4. then OpenFB.init(‘app_id’,‘https://localhost:8100/openfb/index.html’);

but when i run the app as “ionic serve”, it shows a popup for my facebook app. when i click okay the it shows
Cannot GET /openfb/index.html?
inside that popop.

So i think the callback url is the problem here. Can anyone please help me with this???
Thanks in adv!
