Getting Connections details with get_active_connection/get_active_connection_v2 failing

Hi All, Trying to get the connection details through perl iControl SOAP API getting result as InvalidArgument.

Below is the code snippet:

my $ConnectionDefn = {

clientside_client => {

   address => '192.168.4.238',
   port    => '59492'

},

clientside_server => {

   address => '192.168.4.242',
   port    => '4353'

},

serverside_server => {

  address => '192.168.4.242',
  port    => '4353'

},

protocol => 'tcp' };

my $soapResponse = $SystemInfo->get_active_connection( SOAP::Data->name("connections" => [$ConnectionDefn]));

Following is ther error:

SOAP-ENV:Server Exception caught in System::urn:iControl:System/Connections::get_active_connection() Common::InvalidArgument
