After migrating to prefect 3 my flow started reporting success when underlying tasks have failed. My flow contains nested tasks 1 level deep where the parent tasks are generated with a loop using

.submit()

and thus need to run async. The child tasks can run sequentially if needed but currently also use

.submit()

which saves a small amount of time. I cannot use

raise_on_failure=true

because it is only accepted as a parameter in

.result()

or

.wait()

which are blocking and force my code to run sequentially and I cannot use

return_state=true

because then my tasks will return

State

objects instead of `Future`objects which again forces the code to run sequentially. Are there any other options?
