Issue with grant group permission to Site Page

Posted on by webmagic2022

Hello,
I have a Modern SharePoint site with a news page. Employees can post news themselves. I want to prevent employees from editing or deleting news posts from other users. To achieve this, I created a Power Automate Flow that grant uniques permissions for the page item. This works well. However, assigning a SharePoint group with read permissions is not working correctly. I receive this error message.
GroupID is correct.

_api/web/Lists(guid'@{variables('LibGUID')}')/items(@{triggerOutputs()?['ID']})/roleAssignments/addRoleassignment(principalid=14,roledefid=1073741826)

Is this the correct URI?

Check GroupID:

Any Clue

Issue has been fixed by re-creating the URI:

_api/web/lists('@{variables('LibGUID')}')/items(@{triggerOutputs()?['body/ID']})/roleAssignments/addRoleassignment(principalid=14,roledefid=1073741826)

looks like you miss out the item to process upon : @{triggerOutputs()?['ID']}
If I zoom-in your screenshot at the SetGroupPermission action it looks like below.

Have you broken the inheritance on the item first?

BreakRoleInheritance(CopyRoleAssignments=true, ClearSubscopes=true)
