AWSDynamoDB - пустой результат задачи

Question

task = [[task continueWithSuccessBlock:^id(BFTask *task) 
{  
     NSLog(@"%@: Get profile for identity : %@", NSStringFromSelector(_cmd), cognitoUID); 
     AWSDynamoDBObjectMapper *dynamoDBObjectMapper = [AWSDynamoDBObjectMapper defaultDynamoDBObjectMapper]; 
     return [dynamoDBObjectMapper load:[TPLCognitoUserDBO class] hashKey:cognitoUID rangeKey:nil]; 

     }]continueWithBlock:^id(BFTask *task) 
     { 
      if (task.error) { 
       NSLog(@"%@: The request failed. Error: [%@]",NSStringFromSelector(_cmd), task.error); 
      } 
      if (task.exception) { 
       NSLog(@"%@: The request failed. Exception: [%@]", NSStringFromSelector(_cmd), task.exception); 
      } 
      if (task.result) { 

       TPLCognitoUserDBO *cognitoProfile = task.result; 

       if(cognitoProfile) 
       { 
        NSLog(@"%@: User ID %@ ::",NSStringFromSelector(_cmd), [cognitoProfile TPLHandle]); 
        [userIDFound setString: [cognitoProfile TPLHandle]]; 

       } else { 
        NSLog(@"%@: Output has no records in it.", NSStringFromSelector(_cmd)); 
       } 

      } 

     return nil; 

     }]; 

return task;
