Hi, I'm having issues with an ops which returns an object which is not pickable. I add the inmemory io manager to my job and

@job(resource_defs={"my_io_manager": InMemoryIOManager()})

and ops

@op(out=Out(io_manager_key="my_io_manager"))

But now my the op which receives the unpickable object fails
