Quick question: If a `task` is configured with `cache_result_in_memory=False` , can its result only be consumed via `state.result()` / `future.result()` ?
Calling such tasks directly, i.e.. `result = my_task()`,  seems to raise the `MissingResult` error.

I don’t think the error has to do with `cache_result_in_memory=False`. Can you post an example of your code?

I think the error happened because I didn't explicitly set `persist_result=True`. In my case, `taskA` and `flowB` both have `cache_result_in_memory=False` and `flowB` uses the result of `taskA` , and returns it too.
