Camunda 8 python客户端问题

Question

我尝试了camunda社区python客户端，从repo (https://github.com/camunda-community-hub/camunda-8-code-studio/tree/main/src/PythonCloudWorker)。我已经设置了caunda8saas帐户来从repo运行我的任务。

当我尝试运行python文件时，我得到错误，发布错误。欢迎提出任何建议。

问题是我没有传递区域参数，该参数默认为bru-2。

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)
