In prefect 2 0 what is the migration path for running workfl

Question

In prefect 2 0 what is the migration path for running workflows on a simple interval schedule I tried creating a deployment yaml and including a schedule like this ```schedule interval 75 timezone ``` However the flow doesn t actually run and I see a bunch of `Scheduled` flow runs that eventually become `Late`

Jeff Hale · Answer

If they are getting scheduled but showing as late that means the interval schedule is working You just need an agent running for that work queue to pick up the runs

I actually even ran `prefect start lt queue name gt `

Neil Natarajan · Answer

and still flows are not being executed

Neil Natarajan · Answer

they just get marked `Late`

Neil Natarajan · Answer

Do you have an example of a simple local 2 0 workflow that runs on an interval schedule

Anna Geller · Answer

If you re using CLI it s as easy as adding interval 75 to your prefect deployment build command

Anna Geller · Answer

the syntax to start an agent is ```prefect agent start q queue name```

Neil Natarajan · Answer

Actually it seems the correct command is `prefect agent start lt queue name gt ` I tried this however the flows are still not being executed even though in the logs as I mentioned I see the agent started

Neil Natarajan · Answer

My deployment file already has the schedule the flow runs are even being displayed in the Orion UI as `Scheduled` they just never run and become `Late`

Neil Natarajan · Answer

Do you have an example of a flow running on an interval schedule I can look at

Neil Natarajan · Answer

What version of prefect btw are you referencing maybe I am on an older version 2 0 2

Jeff Hale · Answer

Ah that s it Update to 2 1 1 and use `prefect agent start q lt queue name gt `

Neil Natarajan · Answer

i upgraded prefect versions and suddenly my orion ui is glitching a lto

Neil Natarajan · Answer

Can t view the deployments or create workflows from the ui anymore

Neil Natarajan · Answer

The cli seems to be working fine so I am able to move forward but the UI no longer seeems to work as most button clicks result in 404 errors

Jeff Hale · Answer

Hmm Maybe try a hard refresh or logging out and in

Neil Natarajan · Answer

I tried deleting the ~ prefect directory to reset things but the ui still appears blocked as I cannot click on any flow runs as I could previously Button clicks are resulting in 404 errors

Anna Geller · Answer

you can create a new fresh Conda virtual env and try it there and also signing up for Cloud might help as it gives you fewer things to manage <https app prefect cloud >
