Symfony Cache InvalidArgumantException

我需要帮助理解symfony缓存组件 . 我从其他程序员继承了symfony表单的脚本来创建一个项目 . 这个：

class OfferController extends Controller
{
    public function createAction(Request $request) {
        $api_offer = $this->get('gamexp_affiliates.api.admin.offer');

        $api_goal = $this->get('gamexp_affiliates.api.admin.goal');
        $tpl = '@GamexpAffiliates/Admin/Offer/Form/create.html.twig';

        $offer_webmasters = $offer_projects = $offer_goals = null;

        $sendCommonResponse = function(FormInterface $form = null, $code = 200, $headers = []) use ($tpl, &$offer_webmasters, &$offer_projects, &$offer_goals) {

            $response = $this->render($tpl, $form ? array_merge([

我有这个例外：

request.CRITICAL：未捕获的PHP异常的Symfony \元器件\缓存\异常\ InvalidArgumentException：“高速缓存密钥长度必须大于零”在/home/ruslan/Projects/partners_prod/cache/prod/classes.php线1747 {“异常“：”[对象]（Symfony的\元器件\缓存\异常\ InvalidArgumentException（代码：0）：高速缓存密钥长度必须大于零在/home/ruslan/Projects/partners_prod/cache/prod/classes.php:1747） “} []

而且只有在我处于 生产环境 环境时才会发生这种情况 . 在开发中所有工作都很好！最初页面加载正常，但后来我得到ajax请求发生一些额外的数据异常 . 当我使用debuger进行代码时它在$ form-> isSubmited（）点失败 . 在$ form-> handelRequest（）方法之后 . 这个例外的意思是什么？我没有添加缓存任何键！这个怎么运作？我非常需要知道此异常的基本问题 . 请帮帮我吧 . 非常感谢您的帮助！
