AWS Cognito - MFA setup

Question

I use the JavaScript AWS SDK for MFA setup and have 2 issues: First, I update phone number (phone_number attribute with updateUserAttributes method).

It updates but returns empty object instead of (according to docs):

{
    "CodeDeliveryDetailsList": [ 
    { 
        "AttributeName": "string",
        "DeliveryMedium": "string",
        "Destination": "string"
    }
    ]
}

Second, I am trying to send user a verification code with getAttributeVerificationCode with the following payload:

const params = { 
  AccessToken: auth.accessToken,    
  AttributeName: 'phone_number'
}

and I am getting

CustomMessage failed with error
Cannot read property identity of undefined

as error. Any ideas?

For the ones who come across same problem, we could solve it by using cognitoUser.updateAttributes instead of cognitoidentityserviceprovider.updateUserAttributes contrary to the official docs. AWS, especially cognito is premature and lack of docs is another issue for the ones who are considering to use.
