Hi, I’ve been trying to do a facebook login with a custom interface using:

Auth0.authentication().loginSocial(token: “test”, connection: “facebook”, scope: “”, parameters: :]).start { (credentials) in  
print(credentials)  
}

But all I get is this message:  
**Grant type ‘[http://auth0.com/oauth/legacy/grant-type/access\_token](http://auth0.com/oauth/legacy/grant-type/access_token)’ not allowed for the client.**  
I’ve seen that we can’t allow this grant type anymore. So what can I do??  
If anybody has any idea, I’ll take it!
