五、若有更多详细信息，请在下面提供。
如果运行了两年从来没改过配置就报的错，可能是内存、nacos问题，服务重启下应该就可以了。
如果期间做了配置改动功能尤其是路由配置方面的改动，需要找好是改了哪里，先恢复下，然后再重启服务看看是否可以。
从堆栈信息的这一行可以锁定问题：
at org.springframework.cloud.gateway.route.RouteDefinitionRouteLocator.combinePredicates(RouteDefinitionRouteLocator.java:221)
在 Spring Cloud Gateway 的源码逻辑中，每一个路由定义（RouteDefinition）必须包含至少一个 Predicate。
如果没有配置 Predicate，代码在尝试合并断言（combinePredicates）时会去访问一个空的 List，从而触发 IndexOutOfBoundsException: Index: 0, Size: 0。
nacos 和 代码都没动内存的话是充足的现在就是重启后正常了就是担心下次突然又报错所以想问问不升级是不影响使用的吧
不升级不影响使用，但是如果你们的系统公布在外网，可以看下我们的安全手册，修复下漏洞：https://center.javablade.com/blade/BladeX-Safety
另外没有哪个系统能一直运行好几年不用维护的，建议你们3～6个月维护一次（其实就是重启），这样对客户来说你们也对项目上心，会时不时帮他们维护系统。
这两个服务我们一直没有去执行的建议要不要跑起来 路由我们这边一直没添加新的老版本会不会有缺少这个的Predicate需要升级的
不影响，不跑，维持不变就行
嗯嗯 还有一段报错和上面的不一样的你看看有没有什么建议给我们的：

还是一个类型的错误。估计就是运行久了导致的内存或者nacos本身的问题
