我尝试在Cassandra 4.1中使用触发器,但在加载jar文件时初始化失败

Jar档案:https://github.com/felipead/cassandra-logger/releases/download/v0.2/cassandra-logger-0.2.jar
Docker-Compose.Yaml和Cassandra.Yaml:https://github.com/hofstede-matheus/MATB09-postgres-vs-cassandra
hms-cassandra-triggers-1.0.1.jar也会发生这种错误,所以我认为cassandra-logger-0.2.jar没有问题
已尝试使用其他.jar文件,但未成功。

在docker-compose.yaml中使用cassandra:3.0映像解决了这个启动问题。
我认为触发器与 cassandra 4.1版不兼容。
