Thank you for your reply -raise_error helped alot, the code is verbatim from the module webpage, and it does compile if I just have the lines below.

my $ec2 = VM::EC2->new(-access_key => 'wew23232',
                       -secret_key => '3232323',
                       -endpoint=> 'http://ec2.amazonaws.com',
                       );


#Get image
my $image = $ec2->describe_images('ami-469e1d2a');

I also do have an image created and set it as the image code $ec2->describe_images('ami-469e1d2a'), but was getting an error which was solved by sync the server clock.

Now I am getting the error from the modified code

[595] No such device or address, at API call 'DescribeImages')

#!/usr/local/perl-5.23.3/perl

use strict;
use warnings;
use VM::EC2;


my $ec2 = VM::EC2->new(-access_key => 'AKIAJQc',
                       -secret_key => 'J3jCAvb2+six',
                      -endpoint=> 'http://ec2.amazonaws.com',
                       -raise_error=> '1',
                       -region=> 'sa-east-1a',
                        );



#Get image
my $image = $ec2->describe_images('ami-469e1d2a');



# get some information about the image
my $architecture = $image->architecture;
my $description  = $image->description;
my @devices      = $image->blockDeviceMapping;


for my $d (@devices) {
  print $d->deviceName,"\n";
   print $d->snapshotId,"\n";
   print $d->volumeSize,"\n";
