I cannot start a flow run from another flow. Can you please verify my minimal example? I have two flows. This is registered as

flow1

:

#!/usr/bin/env python
# coding: utf-8

import prefect
from prefect import task, Flow
from prefect.environments.storage.local import Local


@task
def task1():
    prefect.context.get("logger").info("hello, task1")


with Flow("flow1", storage=Local(directory="/flows/.prefect/flows")) as flow:
    task1()

if __name__ == "__main__":
    flow.register()

And here is

flow2

:

#!/usr/bin/env python
# coding: utf-8

import prefect
from prefect import task, Flow
from prefect.tasks.prefect import FlowRunTask
from prefect.environments.storage.local import Local


@task
def task2():
    prefect.context.get("logger").info("hello, task2")


with Flow("flow2", storage=Local(directory="/flows/.prefect/flows")) as flow:
    flow1_run = FlowRunTask(name="flow1-runner", flow_name="flow1", wait=True)
    task2.set_downstream(flow1_run)

if __name__ == "__main__":
    flow.register()

When I now run the

flow2

I get an error:
