Authentication failed due to an internal error for challenge "PASSWORD_VERIFIER"

[sagardvora]

Describe the bug
I am implementing aws cognito user pool using custom auth for multi factor authentication.
I have set the authentication type as CUSTOM_AUTH and custom challenge as SRP_A. which in response gives another challenge as PASSWORD_VERIFIER and the procedure fails.

To Reproduce
Steps to reproduce the behavior:
Code for authentication using CUSTOM_AUTH

Map<String, String> authParameters = new HashMap<>();
        authParameters.put(CognitoServiceConstants.AUTH_PARAM_USERNAME, this.username);
        authParameters.put(CognitoServiceConstants.AUTH_PARAM_PASSWORD, password);
        authParameters.put(CognitoServiceConstants.AUTH_PARAM_SRP_A, new AuthenticationHelper(this.username).getA().toString(16));

        AuthenticationDetails authenticationDetails = new AuthenticationDetails(this.username, authParameters, null);
        authenticationDetails.setAuthenticationType(CognitoServiceConstants.AUTH_TYPE_INIT_CUSTOM_AUTH);
        authenticationDetails.setCustomChallenge(CognitoServiceConstants.AUTH_PARAM_SRP_A);
        continuation.setAuthenticationDetails(authenticationDetails);

        continuation.continueTask();

which gives callback in

  AuthenticationHandler authenticationHandler = new AuthenticationHandler() {
       @Override
        public void onFailure(Exception e) {
         .... //exception message ->  Authentication failed due to an internal error
        }
}

Which AWS service(s) are affected?
Cognito User Pool Authentication MFA

Environment(please complete the following information):

• SDK Version: [e.g. 2.8.+]

Additional context
MFA is activated on backend server.

I got the same error when I try to sign in a user with cognitoUser.getSessionInBackground(authenticationHandler)

I saw that this problem was encounter when we try to sign in a user just after verifying him but it's not my case, I closed the app after the verification via signup.

@sagardvora , I saw that you commented saying that the bug fix did not solve your issue. Can you provide logs of the issue when it occurs? Also since this is a custom auth challenge. Can you give details on what the challenges are and what order is expected?

Partial fix has been committed.

Hi @sagardvora @YoanGJ ,
