我需要幫助理解symfony緩存組件。我用symfony表單繼承了其他程序員的腳本來創建一個項目。這：Symfony緩存InvalidArgumantException

我有這樣的例外：
request.CRITICAL：未捕獲的PHP異常 的Symfony \分量\緩存\異常\ InvalidArgumentException： 「緩存鍵 長度必須大於零」 的 /home/ruslan/Projects/partners_prod/cache/prod/classes.php line 1747 {「exception」：「[object] （Symfony \ Component \ Cache \ Exception \ InvalidArgumentException（code： 0）：Cache key length在 處必須大於零/home/ruslan/Projects/partners_prod/cache/prod/classes.php:1747）「} []
而這只是當我在prod環境中發生。在開發一切工作正常！初始化頁面加載正常，但然後我得到一個額外的數據異常發生的Ajax請求。當我用debuger進行代碼時，它在$ form-> isSubmited（）點失敗。在$ form-> handelRequest（）方法之後。這個例外的含義是什麼？我沒有添加緩存任何鍵！怎麼運行的？我強烈需要知道這個例外的基本問題。幫助我，請將其放下。非常感謝您的幫助！
