当我尝试将APIM 2.6.0与流处理器4.3.0集成时遇到一个奇怪的问题
我已经启动了流处理器工作程序节点，并且所有siddhi应用程序都已经部署完毕，并按照Deployment.yml文件中的指定在数据库中创建了表
现在，我已经在同一服务器（Ubuntu）中安装了APIm 2.6.0，并在api-manager.xml文件中启用了Analytics（分析）选项。
启动APIM时，我不断遇到错误：

请问有关错误之处的信息在这里。到目前为止，我为检查此问题所做的工作是：
1）我还更新了client-truststore中的证书 2）在工作节点的部署文件中启用（基于64格式）管理员密码 我仅使用默认密码作为管理员。有人可以帮忙吗
谢谢
