Hey, have a question: • Using Prefect 1.0 • Using

Local

storage and

Prefect Cloud

I want to use

stored_as_script=True

for my flow (pickle storage is not working with an SQLAlchemy object for some reason), and so I need to specify

path

— but that is giving me an error. Sharing the relevant code snippet and error.

with Flow(
        "eco_flow", 
        schedule=schedule, 
        storage=Local(stored_as_script=True, path='~/.prefect/flows/test-flow.py')
    ) as flow:

    cities = ['mumbai', 'new-delhi']
    
    for city in cities:
        data = get_traffic_data(city)  
        clean_data = clean_traffic_data(data)
        insert_to_db(clean_data)

Error after registering the flow:

Failed to load and execute flow run: ModuleNotFoundError("No module named '~/'")

I guess I am defining the

path

incorrectly?

I think you might to spell it out because that is not unpacked and then Prefect tries to import the Flow.

from path... import flow

like that

Discussed this with Kevin on DM and it's now sorted. I had a conceptual misunderstanding re how script storage works. I was pointing to a non-existent flow file as I assumed that prefect will generate it automatically when the flow is registered — which is incorrect. The path needs to point to the flow script. That fixed the error. Thanks Kevin!
