Hi, I'm new to Perl. Please take it easy on me.

I want to automatically login and download a Document from a university Platform, using WWW::Mechanize. The login seems to work, but after that I am not able to call any methods on my mechanize Object (I test this with ->title). I know that the site directly redirects after the login. Is this why the object is "broken"? Do I have to somehow deal with the redirect? 

#!/usr/bin/perl

use warnings;
use strict;
use LWP::Simple;
use WWW::Mechanize;

my $derp = WWW::Mechanize->new();
my $url = "myurl";

$derp -> cookie_jar(HTTP::Cookies->new());
$derp -> get($url);
$derp -> content();
$derp -> follow_link(text=>"loginLink");

print $derp -> title(), "\n";

my @forms = $derp -> forms();

foreach (@forms) {
    my @input_fields = $_->param;
    print "form params are:\n";
    
    foreach (@input_fields) {
            print "$_\n";
        }
}


print "filling in form..\n";

$derp -> field("j_username", "user");
$derp -> field("j_password", "password");

$derp -> submit();

if($derp -> success()) {
    print "success\n";
} else {
    print "something went wrong\n";
}


print $derp -> title(), "\n";

The output is success, but I get the following error: Use of uninitialized value in print at messing_around.plx line 43. I think that submit() returns something crap. Is this because I made a mistake or because of the redirect I should somehow deal with?
