Hi @VadymKuriyDev,

Sorry for the confusion. We need to correct the documentation on that method. The Cognito service does not return userSub (userId) in the confirmSignUpcall.

https://docs.aws.amazon.com/cognito-user-identity-pools/latest/APIReference/API_ConfirmSignUp.html

userSub is only returned from signUp calls. https://docs.aws.amazon.com/cognito-user-identity-pools/latest/APIReference/API_SignUp.html

AuthSignUpResult is re-used for both signUp and confirmSignUp, so we will need to adjust the message on the getUserId method.
