Hi all, I'm having trouble finding any documentation around instantiating flow runs from a server app (fastapi). At present, here's the setup: 1. cloud as the backend 2. local agent + executor 3. web service (fastapi) running inside a docker container on my local machine If I've already registered some tasks by manually running a script, how am I supposed to instantiate flow runs from the web service? The python scripts with the task and flow definitions are also available for flask app

The

StartFlowRun

task is actually for starting a flow run from a flow run. I believe you're just looking for https://docs.prefect.io/orchestration/concepts/flow_runs.html#core-client

thanks for replying. Through the client, can I create a flow run just on the basis of the flow name, and the latest un-archived version gets instantiated?

It requires the

flow_id

which you'd get when you register the flow. You can query for the latest unarchived run by flow name beforehand if you'd like. There's a user-contributed PR in progress to do this query for you (https://github.com/PrefectHQ/prefect/pull/4146) but you can also just look at the source code at

prefect.cli.run.flow

to see an example of the query needed

oh okay. Yes, already had a look at the code for the

run

cli command. Thanks for the guidance.
