DynamoDB Supplied AttributeValue is empty

I'm using the latest AWS SDK for PHP 2. There are 2 different pages for the DynamoDB documentation

Latest DynamoDB

DynamoDB before 2011-12-05

Even though I'm using the Latest SDK it's behaving like the "DynamoDB before 2011-12-05". Here's the code I'm using which is resulting in the error "Error Type: client, AWS Error Message: Supplied AttributeValue is empty, must contain exactly one of the supported datatypes"

$result = $client->getItem(array(
    'ConsistentRead' => true,
    'TableName' => 'responsys_users',
    'Key'       => array(
        'HashKeyElement' => array(
            'vendor_map_id' => array('N' => '1')
        )
    )
));

I can't find anything in the API specification or online that's helped solve the problem. Any help would be appreciated!

seems that you have two keys in the table, while only one is provided in the request – yegor256
Found out the problem. I need to implicitly give the latest version for the AWS SDK to use the latest version (and unexpected behavior). So i had to set the 'apiVersion' to '2012-08-10' when creating the client otherwise it the latest SDK uses an earlier version of the DynamoDB client – jadent

You have to lock in the version date on instantiation to use the latest. I believe 2012-08-10 is the latest version.
