canal 1.17 版本，通过命令行可以启动 canal.deploy，但是通过 web ui 想通过 rocketmq 来处理 binlog 的话就一直启动不成功，且还原配置后也无法通过 web ui 启动成功

可以看到 第一次是启动成功的，且通过 web ui 可以看到 server 管理里面是启动成功的

2024-12-09 20:40:20.035 [canal-instance-scan-0] INFO com.alibaba.otter.canal.deployer.CanalController - auto notify start huazai_product successful.

当通过 web ui 修改配置：
canal.serverMode = tcp 改为 canal.serverMode = rocketMQ
添加
canal.mq.servers=127.0.0.1:9876
canal.mq.topic=product_sku_to_es
配置后，保存就报错了，如下：

2024-12-09 20:49:32.744 [canal-server-scan-0] ERROR com.alibaba.otter.canal.deployer.CanalLauncher - scan failed
com.alibaba.otter.canal.common.CanalException: com.alibaba.otter.canal.server.netty.CanalServerWithNetty isn't start , please check

还原配置保存后也是同样报错，请问下我该如何排查并解决这个问题呢？谢谢

把日志放开，这样更容易排查写，控制台的日志也打开
