How to import ova file to vcenter or a host using perl VI SDK

I am currently trying this :

=================================================

$ovfMgr=Vim::get_view(mo_ref => $sc_view->ovfManager);
$pdresult=$ovfMgr->ParseDescriptor('C:/test.ova');

print $pdresult;

==================================================

and getting the following response:

=================================================

Odd number of elements in hash assignment at (eval 23) line 9.
Unexpected arguments: C:/test.ova at (eval 18) line 143
