【问题描述】：

我尝试了来自 repo (https://github.com/camunda-community-hub/camunda-8-code-studio/tree/main/src/PythonCloudWorker) 的 camunda 社区 python 客户端。我已经设置了 caumnda 8 saas 帐户来从 repo 运行我的任务。

当我尝试运行 python 文件并发布错误时出现错误。任何建议都适用。

【解决方案1】：

问题是我没有传递默认为 bru-2 的区域参数。

camunda_region = os.environ.get('CAMUNDA_CLUSTER_REGION')

channel = create_camunda_cloud_channel(client_id=zeebe_client_id, client_secret=zeebe_client_secret, cluster_id=camundacloud_cluster_id,region=camunda_region)
