Hi,

It seems like $values is empty here:

github.com

matomo-org/plugin-QueuedTracking/blob/3a179a8156e89b448fe3a7e164b3aeca360535fd/Queue.php#L86-L92

      
        
            foreach ($values as $value) {
                $params = json_decode($value, true);
            
            
    $request = new RequestSet();
                $request->restoreState($params);
                $requests[] = $request;
            }

This seems like a bug, can you please open an github issue here:
