Power Automate Warning "actions in this flow may result in an infinite trigger loop"

Posted on by

I'm really new to Power Automate flows so appreciate any guidance you have.

I have a Power Automate flow that identifies duplicates in a Microsoft List. The process is:

  1. Person fills in Microsoft form
  2. Flow moves information from form to Microsoft list - the Title field being blank (employee ID)
  3. Administrator adds the employee ID (in the Title field) which is a number format
  4. Flow identifies any duplicates employee IDs (in the Title field) by identifying them in a column called 'Is Duplicate' - defaults to No but if it is a duplicate the flow returns the word 'Duplicate'

The flow works - see below/attached - but it has a warning ' actions in this flow may result in an infinite trigger loop. Please ensure you add appropriate conditional checks to prevent this flow from triggering itself'

How can I fix that?

I tried adding it to a schedule to run once a day but the flow got stuck/kept running at the 'sharepoint when an item is created or modified' point.

This is the FLOW:

  1. (sharepoint) when an item is created or modified (added site address and list name)
  2. (sharepoint) get items (added site address and list name), in the Filter Query I added

Title eq '(Title)'

  1. (condition) length(outputs('Get_items')?['body/value']) is greater than 1
  2. (if yes) (sharepoint) update item (added site address and list name) with ID and (is duplicate value = Duplicate)

    You get the warning because you are using the trigger When an item is created or modified and within the same flow you are updating the item, which then triggers it again unless you have taken precautions to prevent an infinite loop. If you have, don't worry about it. If not, then see this How to avoid infinite trigger loop in Power Automate and implement one of the suggestions to prevent updating the item triggering the flow again.

    A simple trigger condition would be where the field Is Duplicate Value is not equal to Duplicate. For example: @not(equals(triggerOutputs()?['body/IsDuplicateValue/Value'], 'Duplicate')
