Logic App Until Connector Behavior

[DiviyanS13]

Hello !!!

I'm Using Logic app Until connector and Condition connector. Condition connector kept inside Until Connector (Nested).

Question:

Scenario-1:

If any of the connectors under "Condition" failed before the last iteration and if the last iteration of the loop "Success"/ "Skipped" then the whole while loop marked as "Success". Even though it has the failed iterations previously. Finally the logic app run also marked as "Success".

The Run ID: "08584753603580670935562390888CU11" has failed iterations on 2 & 4. Success iterations are 1, 3, 5

Run history:

Scenario-2:

If connectors under "Condition" failed in the last iteration, the whole while loop marked as "Failed". Even though if all the previous iterations are "Success". Finally the logic app run also marked as "Failed".

The Run ID: "08584753596646149685616977734CU12" has success iterations on 1, 2, 3 & 4. Failed iteration is 5

Run history:

From the above tests, I assume only "Until" loops marked as failed when the last iteration status is "Failed".

Can anyone explain the behavior of Until Loop connector and its fair use/best practices.....
