我想测试 Zeebe(camunda 版本)然后我按照以下文档中描述的步骤进行操作。简而言之,我将 Zeebe 作为基于命令的 docker 容器运行docker run --name zeebe -p 26500:26500 camunda/zeebe:latest。
查看最初的日志,一切似乎都运行良好。但是,当我尝试使用 Chrome 访问代理时,我可以在日志中看到以下错误:

我使用 zbctl (zbctl status --insecure) 检查了 Zeebe 状态,它看起来很健康:
Cluster size: 1
Partitions count: 1
Replication factor: 1
Gateway version: 0.23.0-alpha2
Brokers:

有没有人见过这个问题?
