Describe the bug / error

Power Automate Flow that triggers on modified of SharePoint list item, updates same item with use of ValidateUpdateListItem endpoint. Since begin this week (that we noticed) it causing the flow to get triggered again.

It seems that this has been logged before in Oct 2021 #7424 and Nov 2021 #7527 Both with comments far into 2024. I tried to include the Author, Editor and Modified fields in the update. All together and one by one, but no change in the outcome.

I used this for multiple clients of different tenants. I now tested this on 2 different tenants and both solutions that use this endpoint in flows, are flows that keep being triggered.

Does anyone notices this problem on their tenants? Is something missing from my code, that wasn't needed till last week or so?

Steps to reproduce

1. Create SharePoint List: Clients
2. Create Power Automate flow > Automated cloud flow > When an item or a file is modified
3. Add action Compose

Inputs:

[
{
"FieldName": "Title",
"FieldValue": "Test 123"
},
{
"FieldName": "Modified",
"FieldValue": "@{addMinutes(triggerOutputs()?['body/Modified'], 120, 'yyyy-MM-dd HH:mm:ss')}"
},
{
"FieldName": "Author",
"FieldValue": "[{'Key':'@{triggerOutputs()?['body/Editor/Claims']}'}]"
},
{
"FieldName": "Editor",
"FieldValue": "[{'Key':'@{triggerOutputs()?['body/Editor/Claims']}'}]"
}
]

5. Add action 'Send an HTTP request to SharePoint'
   Site address
   Method: Post
   Uri: /_api/web/lists/getbytitle('Clients')/items(@{triggerOutputs()?['body/ID']})/validateUpdateListItem()
   Headers: None, also tried:
   { "Accept": "application/json;odata=verbose", "Content-Type": "application/json;odata=verbose" }
   Body:
   {
   "formValues": @{outputs('Compose')},
   "bNewDocumentUpdate":true
   }

Expected behavior

Flow not triggered after HTTP request is send to update the list item.
