Hi - we're seeing some duplicate scheduled flow runs in Prefect cloud. For example, this flow is supposed to run once a day, but we're getting duplicates.

Thanks for the report Mark, I'll flag this and follow up with our cloud team.

Hey @Mark McDonald - could you share a Flow Run ID for one of the duplicated runs, maybe

cuddle-pony

?

sure! here you go - scheduled duplicate flow runs: aa3bfb9d-60cc-4c49-8605-0db385735e97 (outgoing-civet) 268d0fe0-8ca6-415d-84b2-36173aa5bfde (capable-horse)

interesting, I’m not seeing any duplicates for this flow id (

a15ea4fb-4085-42a1-aa1f-43f6ec0df734

). The two IDs you provided have distinct scheduled start times: - outgoing-civet: “2020-12-09T120000+00:00” - capable-horse: “2020-12-10T120000+00:00"

Perhaps you got two from different days - may want to compare a duplicate, perhaps

cuddle-pony

and

dark-chinchilla

?

i couldn’t find those for that flow ID; I even searched across all runs for the flow group and I couldn’t find any with those names

sorry for the slow response!

Very very interesting, thanks for digging this example up - I don’t have a full story for exactly how this occurred, but on the bright side I believe I do understand how to fix it! It might take a few days to get out the door but I’ll let you know as it progresses

thanks, Chris

Hey @Mark McDonald - yes, apologies for not following up sooner; we released the fix early yesterday!

awesome. thanks!
