Hello, is there a reason that deployments can show up with a red dot on the UI, with the error message "This deployment has not been polled in the past 60 seconds"? I can't find anything in the docs that explains it.

when a worker is pointed a at a work pool/work queue that a deployment is on, it regularly polls the prefect api to see if there are any scheduled runs of that deployment. similarly, a deployment built from a served flow has a polling process that asks about scheduled runs. so the red dot/not ready state means nothing that should be checking for scheduled runs of those deployments has done so recently

sorry I'm not sure i follow! so does the red dot basically mean that there is nothing scheduled, or that nothing is checking the scheduling?

that nothing is checking the scheduling. in most cases, a process you run yourself (agent, worker, flow server) has that responsibility

ok cool. so i have a worker for the work-pool that the deployment uses, and that's green, as are other deployments on that same work-pool. Why would this one deployment be red?

I'm facing the same problem since upgrading to the latest Prefect version
