This is a real error. If a template was created, the job is complete. Instead of crashing by tried to access the job id, as though {{DataflowPipelineJob}} doesn't know it made a template, it should instead return successfully. Or perhaps there is another design choice. But just crashes does not make sense. Probably {{DataflowRunner}} should not return a {{DataflowPipelineJob}} at all in this way.
