use Image::Magick with perl on Ubuntu - perl

Question

Image::Magick module is installed.
I do see the perldoc if I type:
perldoc Image::Magick
While trying to use it with a Dancer2 application I don't get any results.
A simple test script does compile but except my hello I don't get to see any results or warnings? What am I doing wrong?
#!/usr/bin/perl
use strict;
use warnings;
use Image::Magick;
print "hello!\n";
my $image = Image::Magick->new;
$image->Set(size=>'100x100');
$image->ReadImage('xc:white');
$image->Set('pixel[49,49]'=>'red');
$image->Write("cool.jpeg");
Below I provide the relevant parts of the code for the Dancer2 app. On my local (OS X) system everything works fine. On the server the Image::Magick part is not functioning.
As per request the way I use Image::Magick with Dancer2..
package myDancer;
use Dancer2;
use Dancer2::Plugin::Database;
use Dancer2::Plugin::Auth::Extensible;
use Data::Dumper;
use Image::Size;
use Image::Magick;
use File::Basename;
use File::Spec;
use FindBin;
use File::Copy qw(move);

I tested your code and in the directory where my perl file is, it generated a new jpeg file.
I can suggest checking if your file and directory have the needed permissions for writing new files.
P.S. I am using FreeBSD 13
