Hi,all After upgrading of Prefect 2 to 3, "run-graph" always say "This flow run did not generate any task or subflow runs" at a "Runs" pane with Deployment on Kubernetes Worker. Somehow but when I execute same flow at other workload, it works. why? woker "run-graph" show: Local Execution. does not show: Kubernetes Worker

Hey @syakesaba - this could be a few things; we've gotten some similar reports that we're working on here: https://github.com/PrefectHQ/prefect/issues/15153, so you might start by reading that thread and seeing what applies to your situation. Given that you have a workflow that works fine on some workers but not others, I'm guessing this is an issue with websockets not connecting properly

Thank you @Chris White . I' ll check that!
Thank you @Chris White as you said, I got same ERROR of the issue. 200003.634 | ERROR | GlobalEventLoopThread | prefect._internal.concurrency - Service 'EventsWorker' failed with 10 pending items. and I figure that the error not occur if I ran flow at kubernetes worker in same kubernetes prefect server. So it seems to be a connectivity issue of my machines between worker and server. (There is an SSL accelerator and I put custom environment variable PREFECT_API_TLS_INSECURE_SKIP_VERIFY) Thank you

feel free to open a new issue on GitHub if you want to investigate deeper there, or if you figure out the root cause!
