AWS Cognito Invalid identity pool configuration

I am using the AWS Javascript API and trying to get the assigned cognito id:

AWS.config.credentials.get(function(err) {
    if (!err) {
        console.log("Cognito Identity Id: " + AWS.config.credentials.identityId);
    }
});

Why does this result in a 400 error?

{"__type":"InvalidIdentityPoolConfigurationException","message":"Invalid identity pool configuration. Check assigned IAM roles for this pool."}

I have IAM roles configured for authenticated and non-authenticated users.

{
"Version": "2012-10-17",
"Statement": [{
    "Action": [
        "mobileanalytics:PutEvents",
        "cognito-sync:*"
    ],
    "Effect": "Allow",
    "Resource": [
        "*"
    ]
}]
}
