Can you provide a reproducer please? Can you maybe debug that InvalidArgumentException?
The easiest way to do so might be to use dump() in the CacheItem::log() method.

Thank you for your help.
See the output below:

    /**
     * Internal logging helper.
     *
     * @internal
     */
    public static function log(LoggerInterface $logger = null, $message, $context = array())
    {
dump($context); // debug
        if ($logger) {
            $logger->warning($message, $context);
        } else {
            $replace = array();
            foreach ($context as $k => $v) {
                if (is_scalar($v)) {
                    $replace['{'.$k.'}'] = $v;
                }
