I'm trying to set

persist_result

to False since the object it return is not compatible with the Pickle serializer. However, I'm receiving the following error. I'm running on 2.7.2.

Flow could not be retrieved from deployment.
Traceback (most recent call last):

    @task(persist_result=False)

Hm that’s really weird we have extensive coverage of that in tests.
