数据流似乎陷入困境 - 无服务器数据分析实验室2c

Question

我正在完成Coursera课程“使用Google BigQuery和Cloud Dataflow进行无服务器数据分析”和Lab 2c（以及之前的实验室）都无法完成隐藏的消息

The  Dataflow appears to be stuck. Please reach out to the Dataflow team at

我的Cloud Shell启动内容如下所示。请注意SLF4J消息。 “作业”面板报告vCPU时间和其他统计信息，但“步骤”面板和“模块”对话框不显示任何信息。我已经尝试删除整个/ training-data-analyst文件夹并重新创建它并得到同样的问题。
