How to ignore failed tasks?

[AlexanderKri]

Hello,

I start a task several times from a flow. I want the task to run for each iteration regardless of whether the task runs on error or not. For this reason I have implemented a try/except. Now the task runs for each iteration.

The problem is that the task_run that runs on error and reaches "except" is marked green in the Prefect UI.

My goal is to:

1. All task iterations run through regardless of whether some of them ran on error or not,
2. Tasks that ran on error are marked as such in the Prefect UI e.g. by marking the task_run red,
3. A certain action should happen if a task has run on error (send email),
4. If at least one task_run has run on error, then the whole flow should be set to Failed,
5. A certain action should happen if the flow is failed (send email).

Is it possible to achieve this with Prefect?

@task
def start_task(path):
    try:
        #do something
    except:
        #do something
        
@flow
def start_flow(paths):
    for path in paths:
        start_task(path)
