Подскажите как исправить следующую ошибку - Unknown type ''! at 1 at /var/www/html/dir/include//Serialization.pm line 161 Serialization::_parse('Serialization=HASH(0xa9f9cc8)') called at /var/www/html/dir/include//Serialization.pm line 116 Serialization::decode('Serialization=HASH(0xa9f9cc8)', '\x{1}\x{c7}\x{1e}\x{b2}\x{c0}\x{de}\x{9e}\'\x{9d}') called at /var/www/html/dir/include//Serialization.pm line 79 Serialization::unserialize('\x{1}\x{c7}\x{1e}\x{b2}\x{c0}\x{de}\x{9e}\'\x{9d}') called at /var/www/html/dir/include/sub.pm line 83 Ломаю голову - не могу понять из-за чего:( Может модуль какой поставить нужно?

=head1 NAME
Serialization - simple flexible means of converting the output of PHP's serialize() into the equivalent Perl memory structure, and vice versa.
=head1 SYNOPSIS
use Serialization qw(serialize unserialize);
my $encoded = serialize({ a => 1, b => 2});
my $hashref = unserialize($encoded);
=cut
=head1 DESCRIPTION
Provides a simple, quick means of serializing perl memory structures (including object data!) into a format that PHP can deserialize() and access, and vice versa.
NOTE: Converts PHP arrays into Perl Arrays when the PHP array used exclusively numeric indexes, and into Perl Hashes then the PHP array did not.
=cut
sub new {
my $self = bless({},shift);
return $self;
}
=head1 FUNCTIONS
Exportable functions..
=cut
=head2 serialize($var)
Serializes the memory structure pointed to by $var, and returns a scalar value of encoded data.
NOTE: Will recursively encode objects, hashes, arrays, etc.
SEE ALSO: ->encode()
=cut
sub serialize {
my $obj = Serialization->new();
return $obj->encode(@_);
}
=head2 unserialize($encoded,[optional CLASS])
Deserializes the encoded data in $encoded, and returns a value (be it a hashref, arrayref, scalar, etc) representing the data structure serialized in $encoded_string.
If the optional CLASS is specified, any objects are blessed into CLASS::$serialized_class. Otherwise, Objects are blessed into Serialization::Object::$serialized_class. (which has no methods)
SEE ALSO: ->decode()
=cut
sub unserialize {
my $obj = Serialization->new();
return $obj->decode(@_);
} # End of sub.
=head1 METHODS
Functionality available if using the object interface..
=cut
=head2 decode($encoded_string,[optional CLASS])
Deserializes the encoded data in $encoded, and returns a value (be it a hashref, arrayref, scalar, etc) representing the data structure serialized in $encoded_string.
If the optional CLASS is specified, any objects are blessed into CLASS::$serialized_class. Otherwise, Objects are blessed into Serialization::Object::$serialized_class. (which has no methods)
