Google cloud platform 谷歌云功能未能部署到新区域

我有一个最初部署到us-central1的python云函数。当尝试将此函数部署到us-east4时，在加载代码时，我遇到以下错误：

ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Function failed on loading user code. This is likely due to a bug in the user code. Error message: with_scopes_if_required() got an unexpected keyword argument 'default_scopes'
Detailed stack trace:

我在部署期间传入REGION env变量。在us-central1上运行相同的部署命令没有问题。这些部署之间没有任何代码更改。

在requirements.txt中升级google auth和google-auth-httplib2库修复了此问题。

云功能无法启动。启动时是否初始化了全局值？如果是的话，你能告诉我是哪一个吗？

DATAPROC_WORFLOW_CLIENT = dataproc_v1.WorkflowTemplateServiceClient(
    client_options={'api_endpoint': '{}-dataproc.googleapis.com:443'.format(REGION)})
