Unable to get volumes using vol-get-iter API

[Rutul]

use strict;
use WFAUtil;
use Getopt::Long;

my $Cluster;
my $VserverName;

GetOptions('Cluster=s' => \$Cluster,
'VserverName=s' => \$VserverName,
);

my $wfautil = WFAUtil->new();
my $server=$wfautil->connect($Cluster,$VserverName);

my %inputhash = ('owning-vserver-name' => $VserverName);
my %volidattribhash=('volume-id-attributes' => \%inputhash);
my %volattrib=('volume-attributes' => \%volidattribhash);
my %query =('query' => \%volattrib);

my $result=$server->volume_get_iter(%query);

$wfautil->sendLog("INFO",$result->{'attributes-list'});

Is the code fine or there is anything i need to change ?

Also I am gettting error as : 18:00:21.894 ERROR  [Delete Volumes based on Vserver name] Failed executing command. Exception: No definition for typedef is-cft-precommit found at C:\Program Files\NetApp\WFA\perl\nmsdk/OntapClusterAPI.pm line 78812, <STDIN> line 1.

Any inputs on this would be appreciable
