Hello @rizu66

How did you serialize it and where did you store it? The error indicates that it maybe miss some characters. (But I didn't manual try to deserialize it so I can be wrong)

There will be many error possibilities try it with

try {
    $unserializedData = unserialize($serializedData);
} catch (Throwable $e) {
    // Handle the error here
    echo "Error: " . $e->getMessage();
}

also grip on json_encode instead of serialize

The data appears to be truncated as it ends abruptly with "XXXX XXXX XXXX 1301 ". Ensure that the full serialized data is being passed to the unserialize() function to avoid issues related to incomplete data.
