I get the following error when I try to register a flow. Any ideas? TypeError: can't pickle JavaField objects

Hi Matthew - your flows must be pickleable to register with a Prefect backend, and it appears your flow or one of your tasks has a non pickleable attribute

Thank you, it is using jdbc. is this a problem you think?

Hmm no I don’t think so but you might need to be careful - I recommend not initializing any objects outside of your tasks / your task’s run methods

can the shelltask run windows commands?
