wso2 - Siddhi - 尝试部署时业务规则管理器失败

Question

WSO2 业务规则管理器在部署时失败。我正在使用 Docker 来通信 WSO2-dashboard 和 WSO2-worker。

错误日志显示以下内容:

Answer 1

如果业务规则管理器创建的 siddhi 应用程序不正确，则可能会发生这种情况。 出现这种情况的一个可能原因是使用无效的 siddhi 应用模板来创建业务规则。

因此，您可以检查以下内容吗？

1. 通过填写模板化 siddhi 应用中的模板化字段来创建 siddhi 应用。
2. 将该 siddhi 文件复制到 $SP_HOME/wso2/worker/deployment/siddhi-files 目录。
3. 启动工作线程运行时。

如果模板存在任何问题，它的工作人员将无法部署该 siddhi 应用程序，并且会记录相关错误。
