Hi 👋 Anyone had success with running Prefect with uv (https://docs.astral.sh/uv/)? I'm running a python file using

uv run jobs/test_flow/test_flow.py

and getting the error

Unknown setting 'PREFECT_SERVER_ALLOW_EPHEMERAL_MODE'

. It fails just by importing from prefect, not even calling any function. I'm using prefect==2.19.9. Attaching screenshots of the test_flow.py and the error. Any help would be much appriciated.

Hey, I don't believe that

PREFECT_SERVER_ALLOW_EPHEMERAL_MODE

is a

2.x

setting. I think it's only from prefect versions that are

>3.x.

You may need to delete that from your profile (normally under

~/.prefect/profiles

) to use

2.x

@Jake Kaplan Thanks. I'll try that.
