Hi all,

I already had issues with this code and got help (see http://www.perlmonks.org/?node_id=1176056) but I get a new error now and hope it is ok to open a new post for this the new issue.

Perl Version 5.10.0. causes the error:

yyy.pl
Type of arg 1 to keys must be hash (not array dereference) at yyy.pl l
+ine 22, near "})
                                "
Execution of yyy.pl aborted due to compilation errors.

Code: 

use strict;
use warnings;
use Data::Dumper;

my %REST_storage;

my $json_decoded = {
          'data' => [
                      {
                        'svpIp' => '10.1.1.1',
                        'model' => 'xyz',
                        'storageDeviceId' => '800000058068',
                        'serialNumber' => 58068
                      }
                    ]
        };

            print Dumper $json_decoded;
            for my $key1 (keys %$json_decoded)
            {
                print "key 1:  $key1 + $json_decoded->{$key1}\n";
                for my $key2 (keys @{ $json_decoded->{$key1} }) 
                {
                    print "key 2:  $key2 + $json_decoded->{$key1}[$key
+2]\n";
                    for my $key3 (keys %{ $json_decoded->{$key1}[$key2
+] }) 
                    {
                        print "key 3:  $key3 + $json_decoded->{$key1}[
+$key2]{$key3}\n";
                        $REST_storage{$key3} = $json_decoded->{$key1}[
+$key2]{$key3};
                    }
                }
            }
            
print Dumper %REST_storage;

I undestand that I need hash instead of array for

for my $key2 (keys @{ $json_decoded->{$key1} }) but I do not know how to solve it.

Thanks for help.

kind regards deMichi
