Hi, How i can store all task result of flow in specific S3 prefix?

The flow location needs to be defined at registration time or templated to be filled at runtime. If you know the prefix at registration time, you can just add it to the string you set. If you need it at runtime, i think you need to do it through a Parameter as shown here

Shall i pass same location to all tasks?

If you provide the same location to all tasks, it will overwrite. It won’t differentiate, but you can add the

task_run_id

if you want

Can you share the template for adding task_run_id

In the example here , replace with

@task(result=LocalResult(location="{task_run_id}.prefect"))
def downstream_task(x):
    return [i * 10 for i in x]

ok Thanks
