Hi,

I had a nice code working but after testing on a differnt Perl Version I get some errors.

#$json_decoded is a refrence
#$json_decoded =             
#        {
            #
            #  "data" : [ {
            #
            #    "storageDeviceId" : "800000050679",
            #
            #    "model" : "modelname",
            #
            #    "serialNumber" : 12346,
            #
            #    "svpIp" : "10.1.1.1"
            #
            #  } ]
            #
            #}
                
            for my $key1 (keys $json_decoded)
            {
                # key1 = data
                for my $key2 (keys $json_decoded->{$key1}) 
                {
                    # key2 = 0 .. x
                    for my $key3 (keys $json_decoded->{$key1}[$key2]) 
                    {
                        # key3 = storageDeviceId,model,etc
                        $REST_storage{$key3} = $json_decoded->{$key1}[
+$key2]{$key3};
                    }
                }

That worked fine on server 1. On server 2 I got message "keys on reference is experimental" 3 times (on every line with "keys ...") and I learned to use ...

 keys %{ $json_decoded }

instead of ...

keys $json_decoded

This works on both systems.

But when I change to ...

 keys %{ $json_decoded->{$key1} }

instead of ...

keys $json_decoded->{$key1}

... I get the message "Script died: Not a HASH reference at".

Can you help me with the right syntax please to get it run on every Perl version?

Thanks & regards
