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

错误日志显示如下：

Answer 1

如果业务规则管理员创建的 siddhi 应用程序不正确，就会发生这种情况。一个可能的原因是使用无效的 siddhi 应用程序模板来创建业务规则。

因此，您可以检查以下内容吗？

通过在您的模板化 siddhi 应用程序中填写模板化字段来创建一个 siddhi 应用程序。
将该 siddhi 文件复制到 $SP_HOME/wso2/worker/deployment/siddhi-files 目录。
启动工作器运行时。

如果模板有任何问题，它的工作人员将无法部署该 siddhi 应用程序并将记录相关错误。
