Hello prefect community, I am using "manual_only" trigger for the first time and I noticed that when I resume the flow, the variables computed downstream the manual task are not kept in memory. Is that the correct behaviour or am i doing something wrong?Should i take a look how to persistently cache these previous results (https://docs.prefect.io/core/advanced_tutorials/using-results.html) or there is a simpler solution? Thank you for your help!
My flow is as follow:
Copy code
@task()
def f():
  return [1,2,3]
@task(trigger=manual_only)
def g(list):
  return [l+1 for l in list]

with Flow(..) as flow:
  list_for_g = f()
  new_list = g(list_for_g)
and in the logs i can see that the "list_for_g" is None when passed through the task g
k

Yeah I think you need a result configured here because it’s a new python process that starts so it needs to retrieve it from. somewhere
