Let me ask my question better: I appear to be hitting new errors where task results cannot be persisted because the inputs are not pickle-able to make a cache key. • Question 1 - this seems to be new behavior. Did something change where task results are persisted by default (I did not set any retry behavior and I don't want/expect these tasks to be rerun at this point, though I hope to add that functionality in the future) • Question 2 - I see an argument (

results_serializer

) to create a serializer for my task's outputs, but in order to make the inputs "pickle-able" for a retry attempt, I would need an

args_serializer

option which I don't see anywhere.
