Failure parsing GetObject response

[wbo...@gmail.com]

Using phRETS 2.0, attempting to download media for a given resource.  I issue the following query to the server

$objects = $retsSession->GetObject('Property', 'ExtraLargePhoto', '1329630', '*', 0);
var_dump($objects);

The error I am receiving:

Warning: SimpleXMLElement::__construct(): Entity: line 1: parser error : Start tag expected, '<' not found in <path>\vendor\troydavisson\phrets\src\Http\Response.php on line 31

Attempting to download just the location doesn't work either.  It's almost like the response body is missing the reply code for the first object

Is there a setting I need to add when creating the session to have it not strip the first part of the response?
