我有一个新的 Opscenter 安装。将我的“现有集群”添加到 opscenter 后，我收到以下错误对话框：
Error creating cluster: Cannot read property 'datasource' of undefined
进而
Error getting basic OpsCenter information: Timeout exceeded
我的集群是 Ec2MultiRegionSnitch 集群，我提供了一个外部 IP 地址。文件 /etc/opscenter/clusters/my_cluster.conf 已创建，以下输出位于 /var/log/opscenter/opscenterd.log 中，我不明白为什么 Opscenter 没有显示我的集群：

我是 OpsCenter 产品的开发人员。这似乎是一个错误，我们正在调查它（OPSC-3252 是内部票号，供您记录）。在深入研究此特定路径的源代码时，看起来这可能是权限问题。尝试以管理员用户身份添加集群或禁用身份验证，看看这是否适合您。
