private function encodeLabelValues(array $values): string

if some of $values will be numeric, like status code for example, then it will not work with "false !== ($value = apcu_fetch($key))", because json_encode will return different strings to base64encoder.

i tried this and it works, but i guess it's bad solution. Hope i helped with something.

    //status code to int from string
    if(isset($values[1])){
        $mayBeStatusCode = $values[1];
        $values[1] = is_numeric($mayBeStatusCode) ? (int) $mayBeStatusCode : $mayBeStatusCode;
    }
