I have generated a perl client for a rest api with openapi generator. The slimmed down AuthorizeRequestDTO class is :

package WWW::OpenAPIClient::Object::AuthorizeRequestDTO;

require 5.6.0;
use strict;
use warnings;
use utf8;
use JSON qw(decode_json);
use Data::Dumper;
use Module::Runtime qw(use_module);
use Log::Any qw($log);
use Date::Parse;
use DateTime;

use base ("Class::Accessor", "Class::Data::Inheritable");

__PACKAGE__->mk_classdata('attribute_map' => {});
__PACKAGE__->mk_classdata('openapi_types' => {});
__PACKAGE__->mk_classdata('method_documentation' => {});
__PACKAGE__->mk_classdata('class_documentation' => {});

# new plain object
sub new {
    my ($class, %args) = @_;

    my $self = bless {}, $class;

    $self->init(%args);

    return $self;
}

# initialize the object
sub init
{
    my ($self, %args) = @_;

    foreach my $attribute (keys %{$self->attribute_map}) {
        my $args_key = $self->attribute_map->{$attribute};
         $self->$attribute( $args{ $args_key } );
    }
}

__PACKAGE__->method_documentation({
    'username' => {
        datatype => 'string',
        base_name => 'Username',
        description => '',
        format => '',
        read_only => '',
            },
    'password' => {
        datatype => 'string',
        base_name => 'Password',
        description => '',
        format => '',
        read_only => '',
            },
});

__PACKAGE__->openapi_types( {
    'username' => 'string',
    'password' => 'string'
} );

__PACKAGE__->attribute_map( {
    'username' => 'USERNAME',
    'password' => 'PASSWORD'
} );

__PACKAGE__->mk_accessors(keys %{__PACKAGE__->attribute_map});

I'm trying to create a new object by setting the username and password fields but they always come up undefined !!

my %h= ('username' => 'TEST_USER','password' => 'dsds');
my $authobj=WWW::OpenAPIClient::Object::AuthorizeRequestDTO->new(%h);
print Dumper $authobj;

$VAR1 = bless( {
                 'username' => undef,
                 'password' => undef
               }, 'WWW::OpenAPIClient::Object::AuthorizeRequestDTO' );

The init method does
$self->$attribute
what does that mean ? that it calls a $self->update() and a $self->password() methods? But these do not exist in the code!They are only described in __PACKAGE__->method_documentation
Am I missing something or hasn't the openapi generator generated those two methods?
