Attempting to Facebook login via the webAuth(), just making sure this is a current facebook issue (seems unlikely?) Auth0.webAuth().connection(“facebook”).connectionScope(AuthorizationCoordinator.auth0DBConnection).start { (result) in Logger.log(result, .warning) } ![alt text][1] [1]: /storage/temp/813-screen-shot-2018-01-25-at-120406.png Thanks.

Seems the issue was for some reason, adding a connectionScope would cause the facebook error

The connectionScope allows you to set provider scopes for oauth2/social connections with a comma separated list. In the [Auth0.swift repository] ([Auth0.swift/WebAuth.swift at 931883ba3ac3a48d49152cd83a31badad957e3a5 · auth0/Auth0.swift · GitHub](https://github.com/auth0/Auth0.swift/blob/931883ba3ac3a48d49152cd83a31badad957e3a5/Auth0/WebAuth.swift#L120-L127)) it states: `connectionScope: oauth2/social comma separated scope list: 'user_friends,email'`

Just as an example, you can see more info about the facebook permissions scopes here: [Permissions Reference - Graph API - Documentation - Meta for Developers](https://developers.facebook.com/docs/facebook-login/permissions/)

So this code should work with the latest Auth0.swift library:

```
Auth0.webAuth().connection("facebook")
    .connectionScope("public_profile,email")
    .start { (result) in
        switch(result) {
        case .success(let credentials):
            (...)
         case .failure(let error):
             (...)
          }
    }

```
