我有一个最初部署到us-central1的python云函数。当试图将此函数部署到us-east4时，我在加载代码时遇到以下错误：
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:

这是我代码中的一行，错误是抱怨
DATAPROC_WORFLOW_CLIENT = dataproc_v1.WorkflowTemplateServiceClient(
client_options={'api_endpoint': '{}-dataproc.googleapis.com:443'.format(REGION)})
我在部署过程中传入REGION env变量。使用us-central1运行相同的deploy命令没有问题。在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库修复了该问题。
