Adding another follow up, when I succeed at that time, maybe because of the Prefect agent running in the Kubernetes took the workflow job.
But if you want a Prefect agent in the local take the workflow job, here is the solution ConnectionRefusedError: [Errno 111] Connect call failed ('127.0.0.1', 4200) - #3 by Hongbo-Miao
Hope it saves some people time who ends here.
