Having Error on Facebook Login Integration Service

Hi, I'm having trouble on the Facebook Login for my app. When I login with Facebook, it failed to authenticate. I followed the "How to" guideline on the HCL Marketplace.

I did:

  1. Create an app in the Facebook developer console
  2. Copied and pasted the callback URL from Foundry in the Valid OAuth redirect URLs fields
  3. Get the App ID and App Secret from the developer app and paste it in the Identity Service on Foundry

In the end, the function does not work. I think I have missed some things in here, but I just don't know what is it. I'm new in this HCL development. I'm hoping that is there anyone can help me with this issue? I am very much appreciate for it. Thank you.
