Hey @Ayyanar Thangaraj, could you move the Traceback into the thread to keep the main channel more compact? This tends to happen when you have naming conflicts with your file structure. Do you have a directory named

prefect

? Do you have files named

tasks.py

,

task.py

? These will cause conflicting imports

No @Kevin Kho I don't have anything like above prefect directory and tasks.py, task.py.

How did you install prefect?

pip install

into the venv?

Yes

I just wanna make sure it’s not a directory thing. Could you make a subfolder in flows named something like

test

, put

email.py

there and try running that?
