Flow run shows success inspite of a failed task

[Vignesh-Kathirkamar]

I have created a pipeline that has 8 tasks.

Let's say when task 3 fails while running the pipeline, though at task level I can see a failure state, the flow state shows as successful.

This issue is similar to #5374. I tried the solution mentioned there, which is to use "flow.set_reference_tasks" but ended up getting a error: "Flow run encountered an exception: AttributeError: 'Flow' object has no attribute 'set_reference_tasks'".

If any of the tasks in the flow fails, I want the flow state to change into Failure. Has anyone tried something similar before and found a way?
