Im trying to delete a flow and a deployment. This one: https://github.com/anna-geller/dataflow-ops/blob/main/utilities/maintenance.py When I try to delete via the UI I get

Failed to delete deployments

and if I delete with API I get a TimeoutError. I’ve searched Slack and online, but haven’t found anything similar.

you could do that by selecting all runs from that deployment/flow from the UI and click delete (perhaps try doing it step by step) - the issue here is that if you have a lot of them, Prefect will make a lot of API calls and they may timeout if you try deleting a very large number of runs at once -- we may add a bulk soft delete operation for that later but this is not implemented at the time of writing https://discourse.prefect.io/t/when-i-try-to-delete-a-prefect-deployment-i-get-an-error-failed-to-delete-deployment-how-to-solve-it/2083

but I agree doing it from the UI is clunky - can you try deleting the flow?

this should work - just pass the deployment ID and it will delete all runs one by one:

import asyncio
from prefect import get_client
from prefect.orion.schemas.filters import DeploymentFilter


async def remove_runs_from_a_given_deployment_id(id_):
    client = get_client()
    runs = await client.read_flow_runs(
        deployment_filter=DeploymentFilter(id={"any_": [id_]})
    )
    for run in runs:
        print(f"Deleting run: {run.name}")
        await client.delete_flow_run(run.id)
        print(f"Run with UUID {run.id} deleted")


if __name__ == "__main__":
    deployment_id = "bd413bc3-ae3b-49eb-bddf-56a6c4663af2"
    asyncio.run(remove_runs_from_a_given_deployment_id(deployment_id))

might be worth just waiting for the problem to fix itself 😄 unless you're on self-hosted?

I will not run

for i in {1..500}; do python remove_flow_runs.py; done

then 😇

And thanks for the help!
