Hi Prefect community, I am running into a problem with

PyTest

when trying to build an end to end test on a newly deployed prefect flow. With this code:

from prefect.deployments import run_deployment
def test_flow_deployment(flow_name: str) -> None:
    deployment = run_deployment(name = flow_name)

When I run it through PyTest (e.g.

pytest my_prefect_test.py

) I get the following error:

except httpx.HTTPStatusError as e:
            if e.response.status_code == status.HTTP_404_NOT_FOUND:
>               raise prefect.exceptions.ObjectNotFound(http_exc=e) from e
E               prefect.exceptions.ObjectNotFound

However, when I run

python my_prefect_test.py

in the same terminal, there are no errors and the SDK call successfully reaches the prefect cloud and sets off a flow. Does anybody have any ideas? Prefect version

2.12.4

You're using the test harness in a session fixture somewhere, correct?

Hey Dominic, no I'm not using the

prefect_test_harness
