Issue with checking domain

[TeekieWebHostingSA]

I am utilizing following code:

        if ($epp->check_domain($domainToCheck) == 1) {
            print "Domain is available\n" ;
        
        } else {
            my $info = $epp->domain_info($domainToCheck);
            printf("Domain was registered on %s by %s\n", $info->{crDate}, $info->{crID});
        }
        

And i get the error:

Can't locate object method "check_domain" via package "epp" (perhaps you forgot to load "epp"?) at twhepp.pl line 56.

$epp variable are utilized with my $epp = Net::EPP::Simple->new(i removed the sensitive EPP credentials);
and i am using: use Net::EPP::Simple;

The first line is the relevant one and looks like a Perl syntax error. Can you paste the actual code (with credentials removed)?
