This script with an added "OR" (viz. || "::ERR:Cannot print value::") works
as you'd expect
#! /usr/bin/perl
use strict;
use warnings;
use Template;
my $variables = { nrme => "Manfred", };
my $cmd = 'Hi [% name || "::ERR:Cannot substitute variable::" %], how are
you.';
my $template = Template->new();
$template->process(\$cmd, $variables)
or die $template->error(), "\n";
