【问题描述】：

我的数据流有问题，我需要执行一个作业，我收到以下错误：

Workflow failed. Causes: There was a problem refreshing your credentials. Please check:
1. Dataflow API is enabled for your project.
2. There is a robot service account for your project:
service-[project number]@dataflow-service-producer-prod.iam.gserviceaccount.com should have access to your project. If this account does not appear in the permissions tab for your project, contact Dataflow support.

我已经在项目中创建了服务帐户并获得了许可。

Service account

所以我仍然无法识别此错误。我已禁用 Dataflow API 并重新激活，但仍然没有。或者是否可以重新生成此服务帐户以执行作业？

问候

【解决方案1】：

将服务帐户电子邮件添加到 PipelineOptions 的 service_account_email 选项中。

 def get_pipeline_options(self):
      options = PipelineOptions( )

      gcp_options                                   = options.view_as( GoogleCloudOptions )
      gcp_options.job_name                          = "sampleflow"
      gcp_options.project                           = "etldemo-000000"
      gcp_options.staging_location                  = "gs://<bucket name>/stage"
      gcp_options.temp_location                     = "gs://<bucket name>/tmp"
      gcp_options.service_account_email             = "etldemo@etldemo-000000.iam.gserviceaccount.com"
      options.view_as( StandardOptions ).runner     = 'DataflowRunner'

      return options
