Facebook API error 191

Question

I\'m trying to integrate my project with Facebook. I\'m taking baby steps at first and just trying to login, get a Facebook session, and get some user data. I\'m developing

Answer 1

This is just because of a URL mistake.

Whatever website URL is specified should be correct.

I mentioned website URL as http://localhost:3000/ and domain as localhost, but in my browser I was running http://0.0.0.0:3000/.

When I ran server as localhost:3000 it solved the problem.

As I mentioned, the site URL as localhost Facebook will redirect to the same, if we are running 0.0.0.0:3000, it will rise error that "Given URL is not allowed by the Application configuration".
