mybatis-plus 配置rewriteBatchedStatements=true后，updateBatchById()方法异常

当前使用版本(必填,否则不予处理)

com.baomidou:mybatis-plus-boot-starter:3.4.3.2

该问题是如何引起的？(确定最新版也有问题再提!!!)

最新版本com.baomidou:mybatis-plus-boot-starter:3.4.3.4问题也存在

重现步骤(如果有就写完整)

1.数据库连接配置增加：rewriteBatchedStatements=true 2.查询表内多笔数据 3.将查询结果直接调用updateBatchById()方法，报错

报错信息
