Aws AuthenticationHandler

Question

Я работаю над аутентификацией пользователя на AWS Cognito Android SDK, но получаю ошибку SRP. Я снимаю флажок ADMIN_NO_SRP_AUTH, CUSTOM_AUTH_FLOW_ONLY и USER_PASSWORD_AUTH и по-прежнему получаю сообщение «Ошибка SRP». Есть ли что-то, что я делаю не так? Мой код ниже

   userPool = new CognitoUserPool(getApplicationContext(), "us-east- 
      2_UMicfarEa", "6q46s4k4jgvmliumcf4h4p94rs", 
      "t2dmr2ghna2l145qu4nst2gdr5actogeft7blr3eruv2yrvaye", Regions.US_EAST_2);

   user = userPool.getUser( userName);

   authenticateDetails = new Hashtable();
        authenticateDetails.put("username",userName);
        authenticateDetails.put("password", passWord);
        user = userPool.getUser( userName);



     AuthenticationHandler authenticationHandler = new AuthenticationHandler() {
         @Override
         public void onSuccess(CognitoUserSession userSession, CognitoDevice 
         newDevice) {}
         @Override
         public void getAuthenticationDetails(AuthenticationContinuation 
         authenticationContinuation, String userId) { AuthenticationDetails 
         authenticationDetails = new AuthenticationDetails(userName, passWord, 
         authenticateDetails); authenticationContinuation.setAuthenticationDetails(authenticationDetails);
         authenticationContinuation.continueTask();}
         @Override
         public void getMFACode(MultiFactorAuthenticationContinuation 
         multiFactorAuthenticationContinuation) {
         multiFactorAuthenticationContinuation.setMfaCode(mfaVerificationCode);
         multiFactorAuthenticationContinuation.continueTask();}
         @Override
         public void authenticationChallenge(ChallengeContinuation continuation) {}
         @Override
         public void onFailure(Exception exception) {}
         };
     user.getSessionInBackground(authenticationHandler);
