How do I create a Cognito Identity with Facebook token - facebook-javascript-sdk

Question

I have followed through all the steps in the documentation, user pool for registration through an email/pwd combo (working), configured FB identity provider in both the identity pool and user pool section for identity providers, and implemented the following code example found here http://docs.aws.amazon.com/cognito/latest/developerguide/facebook.html and modified below using my identity pool.
{code}
function facebookLogin(){
FB.login(function (response) {
// Check if the user logged in successfully.
if (response.authResponse) {
console.log('You are now logged in.' + response.authResponse.accessToken);
// Add the Facebook access token to the Cognito credentials login map.
AWS.config.credentials = new AWS.CognitoIdentityCredentials({
IdentityPoolId: 'us-east-1:eb997110-50b3-4e40-97ff-fbaf796da9ef',
Logins: {
'graph.facebook.com': response.authResponse.accessToken // cognitouser.idToken
}
});
console.log('Added FB access token to Cognito.');
// Obtain AWS credentials
AWS.config.credentials.get(function(){
//getCurrentUser();
console.log('Got the aws creds.');
});
} else {
console.log('There was a problem logging you in.');
}
});
}
{code}
I can step through and see the FB token being passed into CognitoIdentityCredentials and there are no errors but a user never gets registered in either my Identity Pool or User Pool.
Am I missing something?

Here is a sample of the code I use for creating Federated Identities in AWS
function loadCredentials(identityPool, provider, accessToken) {
var params = {
/*AccountId: window.appInfo.accountId,*/
//RoleArn: window.ap
IdentityPoolId: identityPool,
Logins: {}
};
params.Logins[provider] = accessToken;
AWS.config.credentials = new AWS.CognitoIdentityCredentials(params);
AWS.config.credentials.get(function (err) {
if (err) {
console.log(err.message);
console.log(err.stack);
}
else
{
console.log("Cognito Identity Id: " + AWS.config.credentials.identityId);
console.log("Worked");
}
});
}
