根据你提供的错误日志，出现了两个问题：

1. java.lang.NullPointerException: null
2. org.redisson.client.RedisException: ERR No such master with that name. channel: [id: 0x2d66827d, L:/172.23.9.103:46812 - R:/172.24.107.11:26379] command: (SENTINEL SLAVES), params: [mymaster]

针对第一个问题，即空指针异常，需要检查代码中的相关逻辑，特别是对于RedissonPromise的使用。确保你正确地初始化和使用Redisson，并且相关依赖项和配置都正确设置。你可以仔细检查代码并查找可能导致空指针异常的原因。

对于第二个问题，即找不到对应名称的主节点（No such master with that name），可能是由于Redis Sentinel配置中的主节点名称与你的代码或Redis配置不一致导致的。请确保在你的Redis Sentinel配置中指定了正确的主节点名称（例如，mymaster）。你可以检查你的Redis Sentinel配置文件，并确保主节点名称正确匹配。

另外，你还可以检查以下几点来解决问题：
- 确保Redis Sentinel服务正常运行，且与Redis服务器连接正常。
- 检查Redis主节点的配置是否正确，并确保主节点处于可用状态。
- 检查网络连接是否正常，确保Redis Sentinel和Redis服务器之间的通信没有问题。

如果以上方法无法解决问题，建议你查阅Redisson官方文档或社区支持，以获得更具体的帮助和指导。
