节点。js无法用Java解密长AES256 GCM消息

Question

关于这个问题： Cannot decrypt AES-256 GCM with Java

Java解密问题似乎只有在加密消息很短（即两个字左右）时才能解决。我试过使用“hello”和“short string”这两个词，这两个词都被很好地解密了。当我试着

Alphanumeric string test1 with more numbers such as 5, 4, 3, 2, 1

Aeadbadtag例外再次出现

编辑：

这个问题与加密消息的长度直接相关。两个词有点夸张，但只要加密消息的长度与这个或更长，Java就会出现异常

已使用节点解密：

this is a longer string to make the encrypted message longer than before
