我正试图在docker中设置一个使用ContentBasedRouting的Debezium源连接器，我正在遵循官方文档。
我在/kafka/connect/debezium-connector-mysql中有以下所有依赖项：
antlr4-runtime-4.7.2.jar groovy-3.0.9.jar
debezium-connector-mysql-1.0.3.Final.jar groovy-json-3.0.9.jar
debezium-core-1.0.3.Final.jar groovy-jsr223-3.0.9.jar
debezium-ddl-parser-1.0.3.Final.jar mysql-binlog-connector-java-0.19.1.jar
debezium-scripting-1.7.2.Final.jar mysql-connector-java-8.0.16.jar
目前，我正在尝试添加具有以下转换的连接器：
"transforms": "route",
"transforms.route.type": "io.debezium.transforms.ContentBasedRouter",
"transforms.route.language": "jsr223.groovy",
"transforms.route.topic.expression": "value.after.name == 'x' ? 'topic1' : null",
"transforms.route.null.handling.mode": "drop"
我得到http状态500和日志：

尝试在没有转换的情况下添加一个连接器(其他一切都没有改变(，结果成功了。我做错了什么？
好的，所以我从干净的环境开始解决了这个问题，因为我可能玩过太多版本的混合游戏。确保我在所有方面都使用Debezium 1.8，也许最奇怪的是，我不得不把所有的Debezium罐子都放在/kafka/libs中的connect容器上，因为出于某种原因，它在/kafka/connect/debezium-connector-mysql中不起作用。。。
