Prefect live debugging

[Mdanic75]

Hi Prefect Team,

I've been working with Prefect for orchestrating my data workflows, and it's been a fantastic experience so far. However, I often find myself in need of debugging the code as the flows are running.

Is there a built-in feature in Prefect that allows for live debugging, or is there a recommended approach to achieve this? Any tips or tools that you can suggest would be greatly appreciated.

Thank you for your support and for the great tool!

Best regards,
Daniel

Hi @Mdanic75 and thank you!

You can achieve this when executing locally for sure: if you set up your prefect profile to point to whatever API you are using and execute a flow interactively, breakpoints will be respected:

# example_flow.py

from prefect import flow

@flow(name="Breakpoint example")
def my_flow(name: str, num: int):
    ### some code
    breakpoint() 
    ### more code

and then executing this flow in your favorite interpreter will both communicate with Prefect's API and respect your break points:

>> from example_flow import my_flow
>> my_flow("chris", 42)
## breakpoint will open as normal

Is that the sort of live debugging you were looking for?
