wso2 - 身份验证框架 WSO2 IS 中的异常

Question

我正在运行 WSO2 IS 5.0.0。我应用了 IS 5.0.0 的 SP 以及为 Identity Server 和 Carbon 4.2.0 发布的所有其他安全补丁。我的环境由 4 台正在创建集群的机器组成(使用启用了粘性 session 的 WKA 成员资格方案和负载均衡器(AWS ELB))。我正在使用 MySQL(不是默认的 H2 数据库)。部署IS的机器是Windows Server 2012 R2(EC2 AWS机器)。我偶尔会在控制台日志中收到以下错误:

我不太确定是什么导致了这个错误的发生。它对我的系统来说并不重要，因为我没有注意到它会导致某种问题或停机。
但是我想知道这是错误还是已知问题？如果是这样，有没有办法通过更新一些配置文件来修复(或应用解决方法)？可能有某种补丁可以修复它？

提前致谢。

我假设当 relyingParty 为 null 时会发生这种情况。尝试像这样将其作为注销请求的查询参数发送。
