Deploy OVF with perl sdk

Hi,

I'am trying to deploy an OVF on Vcenter via perl sdk :

Here is my snippet :

# Get OvfManager

print "Get OVF Manager\n";

my $OVFView=Vim::get_view(mo_ref => Vim::get_service_content()->ovfManager);

But it always return this kind of error :

$VAR1 = bless( {

                 'error' => [

                              bless( {

                                       'localizedMessage' => 'Line 1: Could not parse the document: \'not well-formed (invalid token)\'.',

                                       'fault' => bless( {

                                                           'lineNumber' => '1',

                                                           'description' => 'not well-formed (invalid token)'

                                                         }, 'OvfXmlFormat' )

                                     }, 'LocalizedMethodFault' )

                            ],

                 'virtualApp' => '1',

                 'defaultDeploymentOption' => '',

                 'defaultEntityName' => '',

                 'annotation' => ''

               }, 'OvfParseDescriptorResult' );
