[bug] etcd snapshots

Hi,

I have the following when I try to list the snapshots in the web UI :

omv-engined[133206]: PHP Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /usr/share/openmediavault/engined/rpc/etcd.inc:63

This is the offending part (/usr/share/openmediavault/engined/rpc/etcd.inc) :

                foreach($output as $outputk => $outputv) {
                        $outputv['createdAtTs'] = strpdate($outputv['createdTs'],
                                "Y-m-d*H:i:sT");
                        $result[] = $outputv;
                }

The executed shell command is : k3s etcd-snapshot ls --etcd-snapshot-dir /srv/dev-disk-by-uuid-5c645337-b50b-4cc4-a7e6-8a8c3710d1cb/k8s/etcd-snapshots 2>/dev/null --output json

Which returns a JSON object.

In the current form it returns :

List
v1
Array
Array

I'm guessing something changed in the output of the k3s list command

I came up with the following :

<?php
namespace Engined\Rpc;
require_once("/usr/share/php/openmediavault/functions.inc");

$cmd = new \OMV\System\Process("k3s etcd-snapshot ls --etcd-snapshot-dir /srv/dev-disk-by-uuid-5c645337-b50b-4cc4-a7e6-8a8c3710d1cb/k8s/etcd-snapshots 2>/dev/null --output json");
$cmd->setRedirect2toFile("/dev/null");
$cmd->execute($output);

$output = json_decode(implode('', $output), TRUE);

$result = [];
foreach($output['items'] as $outputk => $outputv) {
    $outputv['createdAtTs'] = strpdate($outputv['status']['creationTime'],
    "Y-m-d*H:i:sT");
    $result[] = $outputv;
}

$cc = json_encode($result);
echo $cc;

?>

I have no clue about PHP and stuff so I don't know how to test this. But the timestamp seems correct, hence it shouldn't return any error when trying to fetch the snapshot list :

"createdAtTs":1715373523
