How to get SUB id in the response after register?

[raviji]

I want to get user pool sub id after register in the below function else part.

this.cognitoUtil.getUserPool().signUp(user.email, user.password, attributeList, null, function (err, result) {
            if (err) {
                callback.cognitoCallback(err.message, null);
            } else {
                //console.log("UserRegistrationService: registered user is " + result);
                callback.cognitoCallback(null, result);
            }
        });

In the below links got info like sub id is available when signup but bit confusion how to get update that, either any SDK have to update or anything have to change the function. I would appreciate if i get that sub id in response.

Take a look at this comment: https://github.com/aws/amazon-cognito-identity-js/issues/335#issuecomment-307523556

You need to update the AWS JS libs
