required attributes not supported

[mscansian]

I have a user pool with "name" as a required attribute, but when I try to authenticate an user I get the following response.

Code:

import boto3
from warrant import Cognito
from warrant.aws_srp import AWSSRP
from warrant.exceptions import ForceChangePasswordException

try:
    cognito_idp = boto3.client('cognito-idp')
    aws = AWSSRP(username='user@email.com', password='mypassword',
                 pool_id='pool-id', client_id='client-id', client=cognito_idp)
    tokens = aws.authenticate_user()
except ForceChangePasswordException:
    tokens = aws.set_new_password_challenge(new_password="mypassword2")

Response:

Traceback (most recent call last):
  File "auth.py", line 14, in <module>
    tokens = aws.set_new_password_challenge(new_password="mypassword2")
  File "/usr/local/lib/python3.6/dist-packages/warrant/aws_srp.py", line 231, in set_new_password_challenge
    ChallengeResponses=challenge_response)
  File "/home/matheus/.local/lib/python3.6/site-packages/botocore/client.py", line 312, in _api_call
    return self._make_api_call(operation_name, kwargs)

    raise error_class(parsed_response, operation_name)
botocore.errorfactory.InvalidParameterException: An error occurred (InvalidParameterException) when calling the RespondToAuthChallenge operation: Invalid attributes given, name is missing

I'm new to AWS Cognito, but I think that I also need to provide the required attributes with this auth challenge. Any ideas?
